find the midpoint, which you do by taking the average in each coordinate i.e. add and divide by 2
OpenStudy (anonymous):
would you add -2 and 8 together?
OpenStudy (anonymous):
Yes. You would use, (x2-x1)/2, and same for the y points. just like he said
OpenStudy (anonymous):
According to the numbers given, the diameter is roughly 8.9 therefore the midpoint or center would be approximately 4.45.
