Question

What is the midpoint between (-3,9) and (3,1)

Answer 1

The x coordinate is the average of the two x values which is 3 in this case since they’re both three. And, the y coordinate of the midpoint is the average of the y values. So add 9+1, then divide by 2. You get 10 divided by 2, which is 5. So the y coordinate would be 5. So the midpoint would be (3,5). Hope I helped! Good luck! :)

Answer 2

$A(-3,9); B(3,1) \\ \\ MP=\left(\dfrac{-3+3}{2}\;,\;\dfrac{9+1}{2}\right)=\left(\dfrac{0}{2}\;,\;\dfrac{10}{2}\right) \\ \\ MP=(0\;,\;5)$
