Answer
The midpoint of the first and last points in the table and the middle entry in the table are the same.
Work Step by Step
RECALL:
The coordinates of the midpoint of the points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula:
$=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$
Use the formula above to obtain:
midpoint $=\left(\frac{0+6}{2}, \frac{-6+12}{2}\right)=\left(\frac{6}{2}, \frac{6}{2}\right)=(3., 3)$
The middle entry in the given table is $(3, 3)$.
Thus, the midpoint of the first and last point in the table is the same as the middle entry in the table.
