Question

JK has endpoints located at J(15,-13) and K(-9,27) what are the coordinates of the midpoint JK.

A.(3,7)
B.(12,20)
C.(1,9)
D.(14,18)​

Answer 1

(3, 7)

Explanation:

The formula for calculating the midpoint of two coordinates is expressed as:

M(X, Y) = [x1+x2/2, y1+y2/2]

Given the coordinates J(15,-13) and K(-9,27), the coordinates of the midpoints is expressed as:

X = 15-9/2

X = 6/2

X = 3

Similarly,

Y = y1+y2/2

Y = -13 +27/2

Y = 14/2

Y = 7

Hence the coordinate of the midpoint is at (3, 7)
