Question

Write an equation of a circle that is centered at (1,-4) with a radius of 10.

Answer 1

Answer:

$(x-1)^2 + (y+4)^2 = 100$

=====================================================

Work Shown:

$(x-h)^2 + (y-k)^2 = r^2\\\\(x-1)^2 + (y-(-4))^2 = 10^2\\\\(x-1)^2 + (y+4)^2 = 100$

You could expand terms out and simplify, but I think it's more handy to leave it in this form so you can easily spot the center and radius from a glance.
