Question

Line a is perpendicular to line b. if the slope of line a is 1/8, what is the slope of line b

Answer 1

-8/1

Explanation:

Perpendicular lines have opposite slopes., meaning the signs are opposite, and the numerator and denominator are flipped.

Here's another example:

If line a had a slope of 4/5, line b would have a slope of -5/4, if the lines are perpendicular.
