Attempt to solve for x! (4,y) and (7,6); slope:4
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
\[\frac{ 6y }{ 74 }=4\] \[\frac{ 6y }{ 3 }=4 \] I just set it up like the normal slope equation, (y2y1)/(x2x1). Now just see if you can solve for y.

Olay, let me try it out for myself to see if I understand it

Wait, I get 6 / 3 how did you get 4?

Psymon Group TitleBest ResponseYou've already chosen the best response.1
You said the slope = 4, right? Well, the result of (y2y1)/(x2x1) is slope. But we already have the slope, so I just set the equation equal to 4.

Ahhhhhh okay I see how you set it up!

And then you subtract the bottom, correct?
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
Yeah, which left me with \[\frac{ 6y }{ 3 }=4 \]Would you know how to use that to solve for y?

My guess is that I multiply 6 and 3
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
Just multiply both sides by 3 to start.
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
That will cancel the 3 out of the denominator of the fraction.

So would it be 18+3y=4
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
Nah. Okay, so we multiply both sides by 3 and it looks liek this: \[\frac{ 3(6y) }{ 3 }=4(3)\]From here, the 3's on the left cancel out and 4 and 3 multiplies to get: \[6y = 12 \] Kinda see why?
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
Yea aha I sorta do, it's because I got 183y=12 when I multiplied it by 3
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
Yeah, but you dont multiply the 6 and the y by 3. Because you have a 3 on top and bottom, they cancel out and become 1. That is the whole purpose of multiply by 3 is because itll get rid of the denominator. It's just like if we had: \[\frac{ x }{ 3 }=3 \]Because x is divided by 3, to get it by itself we do the opposite operation and multiply by 3. dw:1378605836732:dw Same thing with our problem: dw:1378605874087:dw

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
Ahhhhhh okay I see now! And then after I get 6y=12 I add 6 to both sides
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
When I divide y to both sides, would I be dividing y or just y?
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
Well if you have y = 6, it does no good to divide by y or y. If you divided by y you get: \[1=\frac{ 6 }{ y } \] You just want to divide by 1 is all to get y by itself.

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.0
And the final answer will be y=6
 one year ago

Psymon Group TitleBest ResponseYou've already chosen the best response.1
Bingo. Can even test it :3 \[\frac{ 66 }{ 74 }=\frac{ 12 }{ 3 }=4 \] So yep, works :3

Thank you much, you explained very well unlike most people here :D do you have time to help me with another 3 problems I had trouble with?
