Question

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 please

Answer 1

the coordinates of the
endpoint are: (-7, - 2)

Explanation:

The average of the values at the
ends of a line segment serves as
its midpoint.

Answer 2

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).
