Question

What is the slope of a line parallel to the line whose equation is 15x +9y = –162.

Fully reduce your answer.

Answer 1

-5/3

Explanation:

The slope of a parallel line is the same as the slope of this line. It can be found by solving for y:

9y = -15x -162

y = -15/9x -162/9

y = -5/3x -18

The slope of the line is the coefficient of x: -5/3
