I would like to have a graph display a vertical line at a solution to a linear equation (like it does in the regular graphing calculator).
How can I get a math Input to Solve for x AND export it to the graph?
If I can get it to solve, then I can just use number(“a”) and use x=a.
Can you share the activity? And give an example of the expected answer for the math input.
Something like this in the graph CL:
And this in your graph:
0=f(x) should also work
f(x)=0 won’t work because its interpreted as “make a function f(x)” which is then overridden by CL
0 = (x) looks for all of the places where the function defined in CL evaluates to 0.
I thought I had tried that as well, but apparently not. Thanks again, @Jay. (Solution edited to reflect suggestion.)
