Hi! I am trying to figure why the inequalities that appear in the table on screen 3 are graphing incorrectly. For example the inequality x + 2y < 100 , a dotted line should go through the point (0, 50), instead it is going through (0, 49.5). This is happening with all the other inequalities on screen 2. Any assistance would be greatly appreciated! 
Take a look at the x-intercept for the inequality 2x + y <= 100. It looks like it is only not graphing a few of them correctly. It is strange.
