y=2x+1

y=x+4

Here is the linear system that I typed in. Instantly, I had an answer. This is one of the tools that is going to make it easier for my students to say “why do we have to learn this?” 🙂 I like the idea that we can go somewhere and have all of our math questions answered. I can see some benefits to this in my algebra 1 classroom. After teaching the concept and assessing their retention, this tool could be used to go into more depth. Rather then spend time solving the systems we can get the answer and then have discussions that get to the underlying themes to linear systems.
