How to find a slope in a table

During social distancing and everything, my math teacher wants me to self-teach ourselves trigonometry. This app is extremely helpful. SO GO DOWNLOAD IT NOW LIKE RIGHT NOW. And describes the steps which helps with learning how to do the equations, i have voted many times but.

I needed help on home work bit my parents had work so this helped a lot. Like now I know how to do certain questions by myself. This app is totally the best, all I can say is this app literary carried my highschool life, if I didn't quite understand the lesson I'll rely from the help of this app.

But other than that it's amazing, i love using it, this is a lot helpful to students who usually deal with a lot of quadratic as well as cubic equations in their homework.
