To check your work, ask yourself this: if I plug in the slope where the variable is, will I get the same answer? To help you visualize this, just use the formula y= mx+b to help find the slope of a graph, or like I said before, to help check your homework, or anything that has to do with this. This can be a very helpful formula. This equation will help you with everything math, especially Algebra! I am very glad that we are learning this now, so that we know how to do this we will already know how to solve it. I hope that you have learned a lot more than you did before! Until next time!
