@cwrw238 can you help

debbieg · Answer

You need the midpoint of the line segment, right? do you know the formula for the midpoint of 2 points?

anonymous · Answer

midpoint formula is
$$\frac{ x1+x2 }{ 2 };\frac{ y1-y2 }{ 2 }$$

debbieg · Answer

Almost...$$\large \left( \frac{ x_{1}+x_{2} }{ 2 },\frac{ y_{1}+y_{2} }{ 2 } \right)$$
