Question

A line segment with endpoints Q(-6,9) and Q(12,-3) is dilated with the origin as the center of dilation. The resulting endpoints are q(-2,3) and R(4,-1). What is the scale factor?

Answer 1

Each of the coordinates is multiplied by a factor of 1/3 so the scale factor is 1/3. You could also graph the points on a coordinate plane and determine this graphically.
