Find an equation of the circle that has center (-4, 1) and passes through (3, -5)
Lemur [1.5K]

The general equation for a circle with center (a,b) and squared radius k is


(x-a)^2 + (y-b)^2 = k


Here we have


(x- - 4)^2 + (y -1)^2 = k


and the constant is fixed by substituting in the point we know (x,y)=(3,-5)


(x + 4)^2 + (y-1)^2 = (3+4)^2 + (-5-1)^2 = 85


Answer:


(x + 4)^2 + (y-1)^2 = 85
