AI Drawing Prompt Reference

Draw a line and a circle, and mark their intersection points. First, simplify an equation and extract its coefficients and greatest common divisor to derive the line equation. Then, plot the circle and the line, and find the perpendicular line from the circle's center to the line. Calculate the distance from the circle's center to the line and determine the intersection points. Finally, display key coordinates and equations in text boxes.
