Write the equation for the circle with center at ( 8,  6) and radius of 10.
(x+8)² + (y + 6)² = 10
(x+8)² + (y + 6)² = 100
(x8)² + (y  6)² = 100
Find the standard equation for the circle with center on the positive xaxis and passing through the origin with radius of 2.
x² + y² = 4
(x + 2)² + y² = 4
(x  2)² + y² = 4
Choose the appropriate description for the equation.
Given: 10(x  3)2 + 10(y + 4)2 = 100

What is your questions about this test?
It is really easy.
if a,b is the center of a circle of radius r, then the equation is
(xa)^2+(yb)^2=r^2
You should memorize that.

It probably would be easy, but I don't have a teacher teaching me this. I do all my school work online and I just need this class to finish and graduate.
