From All my searching I have figured out a solution to this. I can graph lines but not inequalities like 3x + 2y \< 7. Is there a way without going full screen graphing Calculator?

Here’s an example. It will also handle vertical and horizontal cases.  
In the graph CL:

```auto
#Student input
ineq=parseInequality(input.latex)
#isStrict is false then "...or equal to..."
number(`n`): when ineq.isStrict 1 otherwise 0 
function(`f`): ineq.differenceFunction("x","y")

```

In the graph:

```auto
0<=f(x,y){n=0}
0<f(x,y){n=1}

```

Crap. It works for 1 ineq but it won’t let me define ineq in two places. I want to have 3 ineqs
