Question

If a(97,8) and B(-12,202) is M(54.5,105) the midpoint of ab?

Answer 1

`\begin{gathered} \text{let's remember how to calculate the midpoint:} \\ p=((x_1+x_2)/(2),(y_1+y_2)/(2))\text{ } \\ so\text{ in this case we have} \\ p=((97+-12)/(2),(8+202)/(2))=((85)/(2),(210)/(2))=(42.5,105) \\ So\text{ the answer is no, M is not the midpoint of AB} \end{gathered}`
