Question

The slope of AB is 7/2. Segment CD has endpoints at C(-1,4) and D(3,-10). Are AB and CD parrallel, perpendicular or neither? justify.

Answer 1

CD is parallel to AB if it has the same slope. So compute the slope of CD using the slope formula (which you learned in Algebra I) below.

slope = (y₂-y₁) / (x₂-x₁)

Where (x₁,y₁) are the coordinates of point C and (x₂,y₂) are the coordinates of point D.
