# How do you find the midpoint of A (1,3) and Q(7,9)?

$\left(4 , 6\right)$

#### Explanation:

The midpoint of two coordinates is the mean of the coordinates

for $\left({x}_{1} , {y}_{1}\right) , \left({x}_{2} , {y}_{2}\right)$

the midpoint is

$M \left(\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}\right)$

we have

A(1,3);B(7.9)

$\implies M \left(\frac{1 + 7}{2} , \frac{3 + 9}{2}\right)$

$M \left(\frac{8}{2} , \frac{12}{2}\right)$

$M \left(4 , 6\right)$
