Self Check for Graphing Multiple systems of Inequalities

Questions
1

I am trying to code a second inequality line on slide 6 to graph 5x+15y<=180

I can only put one graph on slide 6. Is there anyone who knows how to code another inequality for the graph?

(Another question: I am struggling to read that graph. Could you make the x-axis go up by 2s to make it easier to read?)

Hi Elyse! I was able to finagle checking for 2 inequalities on slide 6 in the following copy of your activity. It involved changing how shaded regions are added (now you click in a region to shade it) and how the type of the line is changed (clicking on the line changes the type). No luck on getting the x-axis to count by 2s, though I did get the minor axis marks to be by 2s. Maybe putting a label on each point with its coordinates would help clarify for students?

Hope this helps!

The “Step” in the Viewport wrench menu is not very consistent. I see that you only changed the step for the x-axis. @Elyse.Carmack It would also help to make your bounds square (i.e. instead of [-1,37,-1,17] use [-1,37,-1,37]), then having a Step of 2 for each axis gives the result you want. If it ever doesn’t work (usually if putting a Step of 1), you can always fake a grid.
