(3,y) defines a vertical line at x=3 ... all the points at a distance of 12 units from point (-2,9) is a circle

since the line is less than 12 units from the point, the line will intersect the circle in two places

the general formula for a circle of radius r centered at (h,k) is (x-h)^2+(y-k)^2=r^2 ... in this case (3-(-2))^2+(y-9)^2=144

25+(y-9)^2=144 ... (y-9)^2=119 ... ...
