Question

Which of the following equations represents a line that is perpendicular to the line represented by x + 2y = 6 and passes through the point (3 , –4)?

Answer 1

y=2x-10

Explanation:

First change to equation into slope intercept form

2y=-x+6

y=-1/2x+3

slope=2 (beacause it is perpendicular)

y--4=2(x-3)

y+4=2x-6

y=2x-10
