AI Drawing Prompt Reference

Graph three linear inequalities using different colored shaded regions, marking key points labeled A to G in each area. Start by drawing three lines for the inequalities y > x, y ≤ -3x + 4, and y < (1/5)x - 2, shading the regions that satisfy each inequality. Place seven points labeled A to G in each shaded area, ensuring their positions clearly show the division of regions and the geometric representation of the solution sets.
