really? I told you that a circle with center at (h,k) and radius r
has the equation (x-h)^2 + (y-k)^2 = r^2
#1. center at (9,6) radius 2
how is (28) even a point? where did r=9 come from?
You were clearly just picking numbers out of the air
#2. center at (-5,-3) radius 11
1.(X-9)2+(Y-6)=4
CENTER:(28)
RADIUS:9
2.(Y+3)2+(X+5)2=121
CENTER=(28)
RADIUS=10
