AI Drawing Prompt Reference

Draw a coordinate plane with two lines passing through two points, one solid and one dashed. Label the slope and equation of the lines. First, draw a bounding box, then mark two points and connect them with a solid line, showing their coordinates. Next, calculate the slope of the line and display its value next to it. Finally, label the equation of the line as y=mx+b, where m is the slope and b is the y-intercept.
