CD has endpoints C(-3, 4) and D(1, -2). Find the coordinates<br> of its midpoint.

Natalija [7]

Answer:

Midpoint (-1 , 1)

Step-by-step explanation:

Formula: (midpoint)

Let the point A(x , y) be the midpoint of CD.

$x=\frac{x_c+x_D}{2} =\frac{-3+1}{2} =\frac{-2}{2} =-1$

$y=\frac{x_C + y_D}{2} =\frac{4+(-2)}{2} =\frac{2}{2} =1$

Then

A(-1 , 1)
