Answer: D

Explanation:

Point of tangency is where the line on the left touches the circle. Have you ever heard the term "She's going off on a tangent"- it means they only touch the topic(tangent point and go off (tangent line) and talk way off away from where you need to be(circle)

So you can see from the graph the point of tangency (where line touches circle is (-5,0)

the equation for the line is going to be a constant. The line only touches the x-axis never the y-axis at all points it is x=-5

so the equation of the line x= -5
