AI Drawing Prompt Reference

Draw a line with an integer y-intercept. First, randomly select an integer for the y-intercept b, then choose random x and y translation values to determine points A and B. Draw the line f and display its slope. Finally, draw a triangle connecting points A, C, and B, where point C is the intersection of line f and the x-axis.
