How do you find the midpoint of R(7,4), S(11,-10)?

The midpoint $= \left(9 , - 3\right)$

Explanation:

R (7,4) = color(blue)(x_1 , y_1

S(11, - 10) = color(blue)(x_2 , y_2

The midpoint $= \textcolor{b l u e}{\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}}$

$= \left(\frac{7 + 11}{2} , \frac{4 + \left(- 10\right)}{2}\right)$

$= \left(\frac{18}{2} , \frac{- 6}{2}\right)$

$= \left(9 , - 3\right)$
