The equation of a line that is perpendicular to -9x = 15 - 3y is y = -1/3(x) + c.
Given:
-9x = 15 - 3y
3y = 15+9x
divide by 3 on both sides
3y/3 = 15/3 + 9x/3
y = 3x + 5
m = 3
Perpendicular slope m1 = -1/m
= -1/3
substitute m value in y = m1x +c
y = -1/3(x) + c.
Therefore the equation of a line that is perpendicular to -9x = 15 - 3y is y = -1/3(x) + c.
