Answer: -4F and 3
Explanation: combine -F and -3F makes -4F and 14 - 11 = 3
He greatest common factor would be 8
The midpoint of the line having the endpoints

and

is

basically average them
so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2
so the midpoint can be found by doing



the midpoint is
The team starts of with: -9 yards
then they gain 5 yards, so you have to -9 + 5 = - 4
Total : -1 yards
-4 + ? = -1
-4 + 3 = -1
The answer is...
The team gained 3 yards
