Question

PLEASE HELP!! If the endpoints of have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of ?
A. (5, 3)
B. (4, 5)
C.(5, 5)
D. (4, 3)

Answer 1

M refers to midpoint.

$

A(9, 8) \\

B(-1, -2) \\

M(\frac{x_1-x_2}{2}, \frac{y_1-y_2}{2}) \\

M(\frac{9-(-1)}{2}, \frac{8-(-2)}{2}) \\

M(\frac{10}{2}, \frac{10}{2})\Longrightarrow\boxed{M(5, 5)}

$

Hope this helps.
