Point Slope & Slope Intercept

Today in math class we reviewed on point slope and slope intercept. Mr. S gave us a Do Now that required us to make a equation and we had to know what to do and what we were doing. It was pretty easy, but most of the students in my class didn't know what to do and didn't ask questions. We wasted a lot of time and I basically sat there bored out of my mind watching them attempt to slove our Do Now that wasn't even that hard and the only way to get it wrong was 1) You weren't paying attention in class, 2) You don't know what to do and 3) You messed up somewhere in the problem. I know I sound like a complete nerd right now, but really? If you don't even bother to participate or learn in class, get the slope out of here!
