I am very new to using CL; so, I will not be insulted if things are spelled out for me! I want students to create secant equations one screen at a time.
Here’s what I’m doing:
On screen 1, I give the students the graph y=x^2, and a point on the graph (2,4). I ask them to pick a point that is also on the graph.
On screen 2, I want their point to show on the y=x^2 graph and I want them to create an equation that goes through both points. I also require them to use point slope form, with my point (2, 4) in the equation. In other words, they must find the slope and use it in this form: y-4=m(x-2).
Here’s my question: How do I get desmos to carry over from screen 1 my students point and my graph and allow me to ask them to create an equation that goes through the two points?
