Question

using the midpoint formula, solve for the midpoint of the segment with these pairs of endpoints (20,-15) and (-11,-10)​

Answer 1

Answer:

(9/2, -25/2)

Step-by-step explanation:

The Midpoint Formula:  The midpoint of the segment joining points $(x_1,\,y_1)$ and $(x_2,\,y_2)$ is $\left(\frac{x_1+x_2}{2},\,\frac{y_1+y_2}{2}\right)$.

$\left(\frac{20+(-11)}{2},\,\frac{-15+(-10)}{2}\right)$

$(\frac{9}{2},\,-\frac{25}{2})$

By the way, instead of trying to memorize the formula, why not just think the x-coordinate of the midpoint is the average of the x-coordinates of the points. The y-coordinate of the midpoint is the average of the y-coordinates of the points.

The average of two numbers is exactly halfway between them!
