Answer: (3,4)
Step-by-step explanation:
To find the midpoint, you want to use the formula [tex]m=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]. Since we are given the two points, we can plug them in and solve.
[tex]m=(\frac{-1+7}{2} ,\frac{9+(-1)}{2} )[/tex] [add numerator]
[tex]m=(\frac{6}{2} ,\frac{8}{2} )[/tex] [divide]
[tex]m=(3,4)[/tex]
Now, we know that the midpoint is (3,4).
