Question

What is the midpoint of the segment shown below?
-10
(-8,-7)
(-7,-8) -10-
10
OA (-15-15)
A.
O B. (-15,-15)
O C. (-15, -15)
OD. (-15, -15)

Answer 1

Remember that the formula to calculate the midpoint between two points is given by

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

substitute given coordinates

$\begin{gathered} M(\frac{-8-7}{2},\frac{-7-8}{2}) \\ \\ M(-\frac{15}{2},-\frac{15}{2}) \end{gathered}$

The answer is option B
