Question

On a school map, the points (-1, -9), (-1, -1), (7, -9), and (7, -1) represent the four corners of a sand park.

What are the coordinates of the center of the sand park?

(-1, -5)

(3, -4)

(4, -4)

(3, -5)

Answer 1

Since you know the four corners you can use the midpoint formula to find the center. \[\frac{x_1 + x_2}{2} \space , \space \frac{y_1 + y_2}{2}\]
