Find the coordinates of the other endpoint when you are given the midpoint (point M) and one of the endpoints (point P).

P = (2,-3) M = (6,-1)

Find the coordinates of the other endpoint when you are given the midpoint (point M) and one of the endpoints (point P).

                                                   P = (2,-3)       M = (6,-1)

anonymous · Answer

other point should be (10,1)

you find the rise and run to find your slope then you use that slope to find the next point

The missing endpoint, say point Q, is at the other direction of point M, opposite to the direction of point P from point M... distance PM = distance QM, and... the slope of line PM = slope of line QM... all points are collinear... contained in a single line... :)
