Question

Write the equation of the circle centered (7,1) at that passes through (2,-10)

Answer 1

equation for a circle:
\[(x-a)^2 + (y-b)^2 = r^2\]

Answer 2

so you've got your center... which is (a, b)
and you've got a point on the line (x, y)
so sub x y a and b into the above equation to solve for r

= final answer
