Hey Desmos,  
Sorry for the late post, I’m trying to code this graph to correct 3 linear equations. I can only correct the blue line. Can anyone find where I have made a mistake on the purple and red lines?

I’m not seeing the mistake. I had a similar issue with multiple lines (graphed using a pair of points) and a table that I was to impatient to resolve.

I’m not 100% sure what you want to do: just make all the lines intersect at one point and for the student to adjust the points to create those lines?
