Check my answer?
Write the equation of the line passing through point (2,3) and is perpendicular to y=4x+7 in standard form.
I got 4x+y=11; is it right?

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes, so slope of perpendicular line ?

4/1 ?

the product of slope of perpendicular lines = 1

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so m1 * m2 = 1 m1 = 4, m2= ?

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
oh 4!
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
4 my bad
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
no, slope of perpendicular line will be negative *reciprocal*
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so m1*m2 = 1 4m2=1 m2 = 1/4 ok ?

ohk sorry I'm not really good at this I just learned this
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so now u have slope of required line and a point on it, which equation will u use ?

pointslope form? yy1=m(xx1)
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
thats correct! so what u get ?

y(3)=1/4(x2) ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
correct :) now simplify....

y(3)=1/4x  idk/: 0.5?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
(1/4)(2) = +2/4 = +0.5

hartnn Group TitleBest ResponseYou've already chosen the best response.1
y(3) = y+3
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
oh wait.. y+3 = 1/4x  0.5 then would you add 1/4x to the left side? since I have to write it in standard form? ax+by=c?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
1) its y+3 = 1/4x + 0.5 2) yes., add 1/4 x , not 1/4 x
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
ohk so .. 1/4x+y+3=0.5 then add subtract 3 on both sides?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes, correct
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
1/4x+y=2.5
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
0.53 = 2.5
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
or u could first multiply by 4 on both sides
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
oh yeah.. sorry.. and oh ohk if i did that it would be x+y=2
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
let me show you steps: y+3 = 1/4x + 0.5 y+1/4 x +3= 0.5 multiplying 4 on both sides 4y+ x + 12 = 2 now can u solve ahead

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
4y+x=14
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
oh whoops 10
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
you will subtract 12 from both sides, right ?
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
yes, sorry
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so finally, 4y+x=10
 one year ago

Steph_Rawr352 Group TitleBest ResponseYou've already chosen the best response.0
yeah thank you though! (:
