Question

What are the coordinates of the center of a circle whose diameter has the endpoints (1, 4) and (-3, -3)?

A.
(-2, 1)
B.
(-1, 0.5)
C.
(-1, 0)
D.
(2, 3.5)

Answer 1

The answer to your question is: letter B

Explanation:

Data

A (1, 4)

B (-3, -3)

Formula

Xm = (X1 + X2) / 2

Ym = (Y1 + Y2) / 2

Process

Midpoint

Xm = (1 - 3) / 2 = -2 / 2 = -1

Ym = (4 - 3) / 2 = 1/2

Midpoint = center = ( -1 , 1/2)
