Question

Consider the line y=8x-7

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

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

Answer 1

For parallel line slope = 8, for perpendicular line slope = - 1/8.

Explanation:

This given line y = 8x -7 has slope=8.

Parallel lines have the same slope, so for parallel line slope is 8.

For perpendicular line slope should be negative reciprocal, and in this case it is equal - 1/8.

Answer 2

1.8

2.-1/8

Explanation:

Just take the number next to the x for #1 Just take the x away and for #2 just make a fraction by doing this 1/8
