Question

Two perpendicular lines intersect at K(-2,-5). One line has equation y = -5/3x-25/3. what is the equation of the other line?

Answer 1

It is y = 3/5x - 19/5

Explanation:

Perpendicular lines have negative reciprocal slopes. Thus, the slope is 3/5x. Plug in -2 as x and solve for the intercept. It ii -19/5.
