Math Input check for correct for all equivalent equations

I want students to be marked correct for any math input equivalent to the expression “y=180x-360”
So far I am not having any luck.
Here is the activity, and I am looking at slide 6.
As you can see from my CL in iput6 and 6note I have tried a bunch of things!

Thank you for any assistance.

Change your input6 code to read:
correct = f.evaluateAt(3)=180 and f.evaluateAt(4)=360 and f.evaluateAt(5)=540
correct: correct

and then change your 6note code to read:
content: when input6.script.correct “Way to go!:laughing:” otherwise “”

Thank you SO MUCH!!! :smiley:
