Question

Find the slope of a line perpendicular to the line whose equation is 3x−3y=18. Fully simplify your answer.

Answer 1

Slope of the perpendicular line = -1

Explanation:

3x - 3y = 18

-3y = -3x + 18

y = -3x/-3 + 18/-3

y = x +- 6

Slope = 1

The slope of the perpendicular line is negative inverse -1
