Question

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

(-5, 1.5)

(-5, 3.5)

(-6,3)

(-3,1.5)

Answer 1

Answer: LAST OPTION.

Explanation:

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

`M=((x_1+x_2)/(2),(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=((-8+2)/(2),(5+(-2))/(2))`

Evaluating, you get that the midpoint is:

`M=(-3,1.5)`

This matches with the last option.
