Question

A polygon has vertices whose coordinates are A(1, 4), B(4, -1), C(-1, -4), and D(-4,1). What is the midpoint for segment AB?

(5/2, 3/2)

(5,3)

(-5/3, -3/2)

(-3, -5)​

Answer 1

(5/2, 3/2)

Explanation:

A = (1, 4)

B = (4, -1)

((x1 + x2)/2, (y1 + y2)/2) = midpoint formula

(x1, y1) = (1, 4) and (x2, y2) = (4, -1)

((1 + 4)/2, (4 + (-1))/2) =

5/2 , 3/2
