Circle Intersection. Write a program that computes the intersection of a circle with a horizontal line and displays the information textually and graphically.
Input: Radius of the circle and the y-intercept of the line.
Output: Draw a circle centered at with the given radius in a window with coordinates running from -10,-10 to 10,10. Draw a horizontal line across the window with the given y-intercept. Draw the two points of intersection in red. Print out the x values of the points of intersection.
