Explanation:

the coordinates of the midpoint are the average of the coordinates of the endpoints.

let coordinates of C = (x, y ) , then with A = (- 1, 2 ) calculate the average and equate to the coordinates of B (3, 2 )

`(x-1)/(2)` = 3 ( multiply both sides by 2 to clear the fraction )

x - 1 = 6 ( add 1 to both sides )

x = 7

and

`(y+2)/(2)` = 2 ( multiply both sides by 2 )

y + 2 = 4 ( subtract 2 from both sides )

y = 2

coordinates of C = (7, 2 )
