Linear inequalities

I am looking to make sure students enter the correct inequality in the math input box as shown in the graph:
when exp3.submitted and exp3.latex = “y<\fract{1}{3}x-1” “\n\Good work !”
when exp3.submitted “\n\Wrong answer. Please try again.”
otherwise “”

It is not reading the less than symbol. Is there a different coding I need to do for less than. Than how about greater than or equal.

Trying to match latex is fragile for this reason, but you can always type into the calculator and copy/paste that into CL. This is more complex, but less likely to have errors once you’ve got your syntax right.
