What is the midpoint of (-3,7) and (15,-15)

Question

Please explain how you got it!

Answer 1

To find the mid point we just take the average of the coordinates

For the x coordinates we have -3 and 15 The average is (-3+15)/2 which is 12/2= 6

For the y coordinates we have -15 and 7 Average is (-15+7)/2 which is (-8)/2 = -4

So coordinates of the midpoint are (6,-4)
