Question

Assume we have two lines which are perpendicular If one line has a slope of

3, what is the slope of the other line? Enter your answer as an integer of
fraction in lowest terms.​

Answer 1

Explanation:

-3

Answer 2

Perpendicular lines have slopes that are reciprocals and opposite signs. Reciprocal means to flip a fraction. If it is a whole number, put it over 1 and flip it. Then change the sign to its opposite.

You could also do -1 divided by the slope you want to be perpendicular to.
