Other midpoint is (4, -3)

Explanation:

The midpoint is found from averaging the x-values of the endpoints and averaging the y-values.

Write down what has been done to find the Midpoint if one endpoint is (-2, 3) and the other endpoint is (x_1, y_1)

(-2+x_1)/2 = 1 " and "(3+ y_1)/2 = 0

Solve each equation to find (x_1, y_1)

-2 + x_1 = 2 " " 3+ y_1 = 0

" "x_1 = 4" " y_1 = -3

Other midpoint is (4, -3)
