The lines whose equations are y = 3x + 1 and y = -3x – 2 are perpendicular because the product of their slopes, and -3, respectively, is –1. a. Use a graphing utility to graph the equations in a [-10, 10, 1] by [-10, 10, 1] viewing rectangle. Do the lines appear to be perpendicular? b. Now use the zoom square feature of your utility. Describe what happens to the graphs. Explain why this is so.
