A line and a circle intersect at A and B as shown below. Find the distance between A and B.
The circle is x^2 + y^2 = 1, and the line is y = x.
X^2 + Y^2 = 1 IS THE UNIT CIRCLE with center at the origin ...this has a RADIUS of 1
the line y = x passes through the origin
distance between A and B will be : 2 unit
