Question

What is the midpoint between (-8, 5) and (2, -2)?

Answer 1

Answer: LAST OPTION.

Step-by-step explanation:

For this exercise you need to use the following formula to find the midpoint:

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

Given these points:

$(-8, 5)\ and\ (2, -2)$

You can identify that:

$x_1=-8\\x_2=2\\y_1=5\\y_2=-2$

Then, knowing these values, you can substitute them into the formula shown before:

$M=(\frac{-8+2}{2},\frac{5+(-2)}{2})$

Evaluating, you get that the midpoint is:

$M=(-3,1.5)$

This matches with the last option.
