Answer :
Answer:
Answer is (7,9).
Step-by-step explanation:
The midpoint formula for a line is (X1+X2/2 , Y1+Y2/2).
Because every answer has a different X coordinate, you only need to calculate one coordinate. I decided to calculate the x coordinate. So... if you apply the formula... X1+9/2 = 8. Multiply two on both sides to get X1+9=16.
X1 is 7.
