Question

Line c and d are perpendicular. the slope of line c is -2/3. which equation is true?

Answer 1

3/2

Explanation:

If a line is perpendicular to the other it's slope is the inverse reciprocal of the other slope

Answer 2

The slope of line d is 3/2 since the slopes of perpendicular lines are negative reciprocals of each other.

So the correct equation is

-2/3 × slope of d = -1
