Do you know how to form an equation for a circle?
Not really, I didn't understand that part in my math lesson quite well. It's the only thing I'm struggling with.

What is the (h,k) form of the equation of a circle?
The circle's center is not at the origin so we will be using the h, k equation.
\[(x - h)^2 + (y - k)^2 = r^2\]
You just . . . fill it in. This is really all you need to know. If the center is at the origin just use:
\[x^2 + y^2 = r^2\]
You fill in for h and k, not for x and y.
Remember to alternate the signs when necessary!
(x - h)^2 + (y - k)^2 = r^2
(h, k) = center and r = radius
so for when its center is at (2, -4) and it has a radius of 6
plug in h=2 , k=-4 , and r=6 into the circle equation ?? That correct?
Remember that inputting negatives will switch the - to a +
