Question

If the endpoints of a diameter of a circle are (2,10) and (-4,2), where is the center of the circle?

Answer 1

You can find the midpoint of a line segment by taking the average of the coordinates of the endpoints. For example, if you have a line segment from (1,2) to (5,2), the midpoint is at ((5+1)/2,(2+2)/2) = (3,2)
