Modify the programs we wrote in class to do each of the following things: 1. Graph the equation y=3x 2. Graph the equation y=3x+10 3. Graph the equation y=3x again, so that a. if the dots in your graph to 1. were spaced out, now put them close enough together so they look like a line, not separate dots; b. if the dots in your graph to 1. were not spaced out, so they looked like a line, now space them out so they look like separate dots 4. Graph the line segment from the point (20,10) to the point (30,40) 5. Graph the equation y-20 = 3x for y in the range -20 to 40.
