I created this to have student solve by substitution and graphing. The first two pages are the activity together (partner A and B). The second 4 are the SAME, but broken down so that you can print them on separate colors and cut them down the middle to hand out one color for partner A and another for partner B.
This is for math 1/algebra 1. Just a basic intro. I am trying to make "interactive notebook" friendly material. In their journal, written to the side, I'm going to ask them what they notice about the y-intercept. Also, I'm going to ask them about linear versus exponential functions....which they think will increase faster.
