Hi! Is it possible to pull the solution to a system of equations out of a graphing calculator, without manually looking at the graph to see the point of intersection?
I need it to plot a point at the intersection of lines that the students are generating.
You could use xyLine to define the slopes and y-intercepts for each line in the graph, then define your solution in the graph. Just realize that doing so may result in some rounding errors.
(I just solved y=m1x+b1 and y=m2x+b2)
Daniel posted before I could finish, but here was my approach. I’m not sure if you are just using the graphing calculator or if you wanted this in an activity, but it will work for both if you use the function sink.
Thank you both! The combination of these two answers is what I needed.
