AI Drawing Prompt Reference

In a coordinate plane, draw a randomly determined straight line and mark a point on it. Construct a circle centered at that point with a fixed radius, and find the intersection(s) between the circle and the line to obtain additional key points. Display the slope of the line and also show the function value at x = 0. Then choose a random direction angle within a specified range to create an auxiliary line, keeping the focus on checking the relationship between slope and the line’s equation using distance measures between the constructed points.
