Question

No idea on what to do.

Which of the following is an equation of the line that passes through the point (–2, 3) and is perpendicular to the graph of the equation y = 3x – 2? A. y = –13x + 73
B. y = –13x + 113
C. y = 3x + 9
D. y = 3x – 3

Answer 1

A

Explanation:

y=3x-2

or 3x-y=-2

any eq. of line perpendicular to it is

x+3y=a if it passes through (-2,3), then

-2+3(3)=a

a=7

so x+3y=7

or 3y=-x+7

y=-1/3 x+7/3
