17. He just knows. I dunno sry
The length of the diameter = sqrt ( (7-1)^2 + (5 - -3)^2)
= sqrt 100 = 10 units so the radius = 1/2 * 10 = 5 units
so the right side of the equation = 5^2 = 25
Centre of circle = midpoint of the diameter = (-3+5)/2 , (1 + 7)/2 = (1 , 4)
so the correct equation is (x - 1)^2 + (y - 4)^2 = 25
