Given the circle #(x – 6)^2 + (y + 2)^2 = 9#, how do you determine if the line with an equation of x = 9 is a tangent to the circle, a secant to the circle, or neither?
When you're in the form
Knowing this information, we can deduce that the center of the circle is at
If you graph the circle and the line you will get the same answer.
Hopefully this helps!
