Updated: 10/18/2022

Generally, the equation of a circle is (x-a)2 + (y-b)2 = r2

where (a,b) is the centre of a circle, and r is the radius.

So you can use this equation along with a general line equation, y=mx+c, or using the gradient and finding the equation of the normal.

What line meets the circle at exactly one point?

The tangent line. A secant line hits the circle in two places and forms a cord, but the tangent line only hits the circle in one point and is always perpendicular to the radius of the circle which exists at that point.

A line touching a circle at one point?

A tangent line.

What is a line that intersects a circle at only one point?
