Step-by-step explanation:

Givens

The midpoint formula is (x2 + x1)/2 , (y2 + y1)/2 = x_mid,y_mid

y_mid = 1

x_mid = -1

y2= 4

x2 = 2

Solution

(2 + x1)/2 = -1

(2 + x1) = -1 * 2

2 + x1 = -2

x1 = -2 -2

x1 = - 4

====================

(4 + y1)/2 = 1

4 + y1 = 2

y1 = 2 - 4

y1 = -2

Answer (-4,-2)
