the midpoint of CD is E (-1 0) one endpoint is C (5 2) what are the coordenates of the other endpoint

Answer 1

To find the coordinates of the other endpoint, we need to use the midpoint formula. The midpoint formula is given by:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Given that the midpoint of CD is E(-1, 0) and one endpoint is C(5, 2), let's denote the coordinates of the other endpoint as D(x, y).

Using the midpoint formula, we can set up the following equations:

-1 = (5 + x)/2
0 = (2 + y)/2

Solving for x and y:

-2 = 5 + x
x = -7

0 = 2 + y
y = -2

Therefore, the coordinates of the other endpoint D are (-7, -2).
