Question 1:

For this one, we can use the midpoint formula.


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


(\frac{-4+8}2, \frac{8+(-4)}2)


(2,2)

The second choice is your answer

Question 2:


If you draw this on the coordinate plane, we have a right triangle with legs of 12 and 9. This is similar to a 3-4-5 right triangle.

Thus, the lengths 9, 12, and 15.

9 + 12 + 15 = 36

Your answer is the last choice. Have an awesome day! :)
