hartnn Group TitleBest ResponseYou've already chosen the best response.1
can you find slope of any given line ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
like say , x5y = 10 is a line. can you find slope of this line first ?
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Uh no not really... with a quick review I probably can
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
good, so i have x5y =10 i will try to isolate y and bring it in the form y=mx+c where m=slope so, x=5y10 5y = x+10 y= (1/5)x +2 got this ?
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Yeah I got it
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
cool, so can you find the slope of x 3y=9 line ? in same way
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
oh and i forgot to mention, y= (1/5)x +2 comparing with y=mx+c gives, m=slope = 1/5
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
x37=9 3y=x+9 Y=(1/3)x+3
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
So slope would be 1/3 I assume?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
correct! :) now try to find slopes of other 3 lines also! and tell me, so that i will verify :)

4x+2y=5 2y=4x+5 Y(1/2)x+2.5 ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
2y=4x+5 is correct, but then divide both sides by 2 what u get ?

10x5y=8 5y=10x+8 Y=2x+1.6?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
10x5y=8 5y=10x+8 <<<<<<NO! 5y = 10x +8
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
and you would get y=2+2.5
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Ahh okay 10 so the problem would come out with a positive 2x
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes, so the slope will be m= 2 , right ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
4x+2y=5 slope = 2 make a note of all slopes, we'll need them
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
and what about last line ?
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
4x+y=1 Y=4x1
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so, slope =?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
Good! now here's the rule : slope of parallel lines are equal! so, for the last one, slope of line parallel to 4x+y=1 will also be m=4 :) so, for last, the correct option will be `C) m=4` got this ? in same way, can you match the 2nd last and 3rd last ?
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Yeah I got it, Thanks a ton man. You need to be my teacher xD
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
haha, :) but we still require to do the 1st 2 !
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
another rule, `product of slopes of perpendicular lines = 1 ` so, for 1st one we had slope = 1/5 let slope of perpendicular line be m. so, \(\Large m\times (1/5)=1\) find m from here :)
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
1st one is m=1/5? 2cnd one is m=1/3? It seems like these would be the answers but they are not possible to be selected.
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Ahhhh okay
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
because perpendicular lines follow different rule :)
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Well I still don't exactly get how it goes from (1/5) to 1...
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
product of slopes = 1 is the rule so, m (1/5) =1 multiplying by 5, m = 5 got this ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
multiplying by 5 on both sides.
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
I'm confused on the product of slopes part, I get the multiplying on both sides. So like can you explain the product of slopes rule.. I tried looking it up on google but nothing I can comprehend really comes up.
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
if say line 1 has slope M1 and line 2 has slope M2 now if these 2 lines are perpendicular to each other, then M1*M2 =1
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
another way to remember the same thing is, the slope of line is negative reciprocal of the perpendicular line, so, slope of line perpendicular to line with slope 1/5 will be  (1/(1/5)) = 5
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so, thats your 1st one, m =5 for 2nd one, we had slope = 1/3, so m *(1/3) = 1 so, m=3 is the answer to 2nd one :)
 one year ago

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Okay, so basically whenever there is a fraction just take (1/_) blank space number lol
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
you forgot the negative :P 1/ stuff
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
but this only applies to perpendicular lines
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
for parallel lines, slope are equal

Oh I see says the blind man

hartnn Group TitleBest ResponseYou've already chosen the best response.1
i hope you got the entire problem clearly ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
ask if any doubts anywhere

Mttblink Group TitleBest ResponseYou've already chosen the best response.1
Yeah I get it now man thanks a ton
