Question

Find the midpoint: (-1, 9), (7, -1)​

Answer 1

Answer: (3,4)

Step-by-step explanation:

To find the midpoint, you want to use the formula $m=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$. Since we are given the two points, we can plug them in and solve.

$m=(\frac{-1+7}{2} ,\frac{9+(-1)}{2} )$            [add numerator]

$m=(\frac{6}{2} ,\frac{8}{2} )$                          [divide]

$m=(3,4)$

Now, we know that the midpoint is (3,4).
