Quizplus · Accepted Answer

The midpoint formula is $\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)$. For the points $(c, y)$ and $(-5c, 7y)$, the midpoint is $\left( \frac{c + (-5c)}{2}, \frac{y + 7y}{2} \right) = \left( \frac{-4c}{2}, \frac{8y}{2} \right) = (-2c, 4y)$.

Provide an Appropriate Response (c,y)( c , y )(c,y) And (−5c,7y)( - 5 c , 7 y )(−5c,7y)

Provide an Appropriate Response $( c , y )$ And $( - 5 c , 7 y )$
