11Find the Coordinates of an Endpoint The Midpoint Formula can be used to find the coordinates of an endpoint when the midpoint and one endpoint are given.Find the coordinates of Endpoint B, if M = 5 is the midpoint, and A = -12 is the other endpoint.2217 units(a single number line)A-12M5B?Multiply both sides by 2Solve for B
12(The midpoint is always the ordered pair with no subscripts) Let X = (x1,y1) (One endpoint)Y = (-2, 2) (Midpoint)Z = (2, 8) (Other endpoint)(x2, y2)(x, y)(x, y)(x2, y2)(x1, y1)(The midpoint is always the ordered pair with no subscripts)X(?)Y(-2,2)Z(2, 8)(-4, -6)
