AI Drawing Prompt Reference

Draw lines with different slopes to demonstrate positive, negative, and zero slopes. Start by drawing two horizontal lines, then a vertical line. Randomly generate a slope and use it to draw a line, showing its slope and y-intercept. Next, randomly rotate this line to create a new slope, draw the new line, and show the new slope and the distance to the intersection with the original line.
