Example : u have an endpoint at (6,5)......ad the midpoint is (4,2)....find the other endpoint.
midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2 one endpoint (6,5)....x1 = 6 and y1 = 5 other endpoint (x,y)...x2 = x and y2 = y sub into the formula m = (6 + x) / 2, (5 + y) / 2
okay, so the midpoint is (4,2)....so ur x value will equal 4 (6 + x) / 2 = 4...multiply both sides by 2 6 + x = 4 * 2 6 + x = 8 x = 8 - 6 x = 2 <==
midpoint is (4,2)....so the y value will equal 2 (5 + y) / 2 = 2 ...multiply both sides by 2 5 + y = 2 * 2 5 + y = 4 y = 4 - 5 y = -1 <==
