Use the Midpoint Formula three times to find the three points that divide the line segment joining (x1, y1) and (x2, y2) into four parts. Use the result to find the points that divide each line segment joining the given points into four equal parts. (a)
(x1, y1) = (2, −6), (x2, y2) = (5, −9)

(x, y) =

(smallest x-value)
(x, y) =

(x, y) =

(largest x-value)

(b)
(x1, y1) = (−9, −3), (x2, y2) = (0, 0)

(x, y) =

(smallest x-value)
(x, y) =

(x, y) =

(largest x-value)
