Question 196104: The circle is tangent to the y-axis and has its center at (-8,-7). Write an equation for the circle. i tried to find the point of tangency by finding the intersection of x=0 and the line perpendicular to it, but i got y=0 and that seemed really wrong. Thank You

You can put this solution on YOUR website! The circle is tangent to the y-axis and has its center at (-8,-7). Write an equation for the circle. i tried to find the point of tangency by finding the intersection of x=0 and the line perpendicular to it, but i got y=0 and that seemed really wrong. Thank You
-------------------------
The radius is 8, since the center is (-8,-7). That's 8 units from the y-axis.
So it's
(x+8)^2 + (y+7)^2 = 64
