Question

Consider the line y=8x - 4.

What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?

Answer 1

Parallel - 8

Perpendicular - -1/8

Explanation:

If a line is parallel to another then they have the same slope

If a line is perpendicular to another line then the slope is just flipped and so is the sign
