Hey guys new to the forum hoping you can fix my stupidity. SO the first problem asks to find the equation of the circle whose center is on the y axis and that contain the points (1,4) and (-3,2). Give the center and the radius. I can find the radius and write the equation I am just struggling to find the midpoint. The other problem is similar. Find the midpoint of a circle passing through the points (3,1) (0,0) and (8,4). Any help would be greatly appreciated!
