Find the Midpoint (1,1) and (7,7)

$(1, 1)$ and $(7, 7)$

Use the midpoint formula to find the midpoint of the line segment.

$(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})$

Substitute in the values for $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ .

$(\frac{1 + 7}{2}, \frac{1 + 7}{2})$

Add $1$ and $7$ .

$(\frac{8}{2}, \frac{1 + 7}{2})$

Divide $8$ by $2$ .

$(4, \frac{1 + 7}{2})$

Add $1$ and $7$ .

$(4, \frac{8}{2})$

Divide $8$ by $2$ .

$(4, 4)$
