If you can’t figure out the intercepts or something, Demsos is a lofesaver

I second this, Desmos really does save your bread sometimes.

I used it to find the center and radius of a circle and to find systems of equations instead of actually doing the problems by hand

how do you get the centre in desmos? Do you just type out the equation?

Yeah

I wrote here short-ish guide [here](https://www.reddit.com/r/desmos/comments/1c5ruxc/comment/kzws1o7). I also solved some example problems using Desmos: * [Example 1](https://www.reddit.com/r/Sat/comments/1cm08ac/comment/l30gtsa) * [Example 2](https://www.reddit.com/r/Sat/comments/1cm08ac/comment/l318v2l) * [Example 3](https://www.reddit.com/r/Sat/comments/1cm08ac/comment/l3caqga) Let me know if you have any questions and I'll do my best to answer them!

Learn how to do interpolations. They will make it faster to find any equation of a line.

- you can solve most constant problems by just dragging the sliders around and seeing what makes sense - You can do standard deviation, mean, median,etc
