Question

p(3, 9) and q(7, 7) are the endpoints of a line segment. what is the midpoint m of that line segment? write the coordinates as decimals or integers. m = ( , )

Explanation:

Step1: Find x - coordinate of mid - point

Use mid - point formula $x=\frac{x_1 + x_2}{2}$, where $(x_1,y_1)=(3,9)$ and $(x_2,y_2)=(7,7)$. So $x=\frac{3 + 7}{2}$.
$x=\frac{10}{2}=5$

Step2: Find y - coordinate of mid - point

Use mid - point formula $y=\frac{y_1 + y_2}{2}$. So $y=\frac{9+7}{2}$.
$y=\frac{16}{2}=8$

Answer:

$(5,8)$
