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
yes, so slope of perpendicular line ?
anonymous
  • anonymous
4/1 ?
hartnn
  • hartnn
the product of slope of perpendicular lines = -1
hartnn
  • hartnn
so m1 * m2 = -1 m1 = 4, m2= ?
anonymous
  • anonymous
oh 4!
anonymous
  • anonymous
-4 my bad
hartnn
  • hartnn
no, slope of perpendicular line will be negative *reciprocal*
hartnn
  • hartnn
so m1*m2 = -1 4m2=-1 m2 = -1/4 ok ?
anonymous
  • anonymous
ohk sorry I'm not really good at this I just learned this
hartnn
  • hartnn
so now u have slope of required line and a point on it, which equation will u use ?
anonymous
  • anonymous
point-slope form? y-y1=m(x-x1)
hartnn
  • hartnn
thats correct! so what u get ?
anonymous
  • anonymous
y-(-3)=-1/4(x-2) ?
hartnn
  • hartnn
correct :) now simplify....
anonymous
  • anonymous
y-(-3)=-1/4x - idk/: 0.5?
hartnn
  • hartnn
(-1/4)(-2) = +2/4 = +0.5
hartnn
  • hartnn
y-(-3) = y+3
anonymous
  • anonymous
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?
hartnn
  • hartnn
1) its y+3 = -1/4x + 0.5 2) yes., add 1/4 x , not -1/4 x
anonymous
  • anonymous
ohk so .. 1/4x+y+3=0.5 then add subtract 3 on both sides?
hartnn
  • hartnn
yes, correct
anonymous
  • anonymous
1/4x+y=2.5
hartnn
  • hartnn
0.5-3 = -2.5
hartnn
  • hartnn
or u could first multiply by 4 on both sides
anonymous
  • anonymous
oh yeah.. sorry.. and oh ohk if i did that it would be x+y=2
hartnn
  • hartnn
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
anonymous
  • anonymous
4y+x=14
hartnn
  • hartnn
2-12=?
anonymous
  • anonymous
oh whoops -10
hartnn
  • hartnn
you will subtract 12 from both sides, right ?
anonymous
  • anonymous
yes, sorry
hartnn
  • hartnn
so finally, 4y+x=-10
anonymous
  • anonymous
yeah thank you though! (:
hartnn
  • hartnn
