A diameter of circle that has endpoints (-4,12) and (8,-2), as shown below, is in the standard (x,y) coordinate plane. What point is the center of the circle? Explain

• math -

the centre would be the midpoint of the given endpoints of the diameter.

so use the formula for midpoint to find the centre
