Answer:
1,7.5
Explanation:
use the equation (x(1) + x(2) ) /2, (y (1) + y (2) ) /2
x(1) is x sub one or -4 since it is the first x value we are given
x(2) is x sub two or 6 since its the second x value we are given
-4+6=2
2 divided by 2 is one
y(1) is y sub one or 8 since it's the first y value we are given
y(2) is y sub two or 7 since it's the second y value we are given
8+7=15
15/2 is 7.5
this gives you x,y or 1,7.5
