How do I graph the inequality from a math input box into a graph?  
The student’s input is y \< -4x +3 and I would like for them to see the graph after they submit an answer.  
I tried this from an activity that I found, but it did not work.  
latex =  
when expressionInput.submitted expressionInput.latex  
otherwise “”

function(“f”): simpleFunction(latex,“x”)
