Parse ordered triple?

is there a way to check that a student answer (x,y,z) is correct?

Or alternatively, the student will find a, b, c in ax+by+c=0 and I want to find a way to see if it’s correct.

I used ordered pair to check for y=mx+b, but not sure how to go about ax+by+c=0.

If memory serves, no. I tried to implement this a couple years ago and recall not getting anywhere

It is possible to check if ax+by+c=0 is correct. I’ve included an example that checks for 2x-y+1=0. If you would like to check for a different function, just change the two points in the graph component through which the correct line passes.
