Currently, I can pull an equation from a math field into a graph. However, when students put in an inequality, it will not allow the graph to change if the student puts a \<,\> or \<=, \>=. Basically, the dotted or solid will not change even if the students change the sign; it is dependent on my code instead of the student input. **Computation Layer Script** #graphing line from line1 to give all =100 function(“f\_1”): parseEquation(line1.latex). differenceFunction(“x”,“y”) #graphing line from line2 to give all not =100 function(“f\_2”): parseInequality(line2.latex). differenceFunction(“x”,“y”) **Graph inputs** 0 = f\_1 (x,y) 0 \> f\_2 (x,y) ---

Here’s an example that you can look at that may help.
