Question

Find the slope perpendicular to the line x+7y=-3

Answer 1

7y=-x-3
Divide each term in the equation by 7
7y/7= -1/7x -3/7
simplify
y=-1/7x-3/7
use y=mx+b
m= slope
b=y-intercept
m= - 1/7
b= - 3/7

Answer 2

wait sorry you are look for a\the slope perpendicular

Answer 3

That's what I got, but I thought you have to use the reciprocal since it's perpendicular so wouldn't the answer be 7?

Answer 4

yup its perp so it is 7

Answer 5

Okay thanks! (:

Answer 6

mperp=7 see you had it! Good job!
