The midpoint of cd is e(–1, 0). one endpoint is c (5, 2). what are the coordinates of the other endpoint? . explain step by step

The coordinates of the midpoint of a line segment is the average of the coordinates of the endpoints. Calculations for the coordinates of the other endpoint are shown below.
                 abscissa     -1 = (5 + x) / 2         ; x = -7
                 ordinate       0 = (2 + x) / 2         ; y = -2

Thus, the coordinates of the endpoint is (-7, -2).

The difference is 5,100m?
