This is my first time making my own activity and I thought I had it figured out. I copied it and went ahead and put in values so I could test it out. One Slide 1 students enter coordinates for a preimage. Each slide thereafter automatically graphs the preimage from slide 1 and graphs the transformation from the new table. Slides 1 and 2 are PERFECT! Exactly what I want. Two questions:

1. On slide 3 (rotation) why didn’t it graph my new coordinates?
2. On slides 3-4 (rotation/translation) why did it graph the transformation with the same color (it automatically used a second color on Slide 1 which is what I want).

Thanks in advance for helping out a noob!

Hi, the reason slide 3 is not showing the polygon is due to the use of e. If you update to a new letter or to something like e\_1, will work, both in the graph and the CL.  
Slide 3 and 4 the second polygon are both set as red, you will need to set this as a different color:  
if you add in g as a list, you can update the color on the polygon and then you can delete it the g= (shown in images)
