Solving equations using a graph such as y=3x+6. The "6" is your y-intercept, so you would move 6 spaces up on the graph, and then plot that. Then you would move three spaces up and one to the right, since 3x is really 3/1. You would continue doing that. If you wanted to move down, you would just move using inverse operation. So you would plot 3 spaces down and 1 to the left. -3/-1 which is the same thing as 3/1. The formula for slope is y=mx +b. Hope this helped!
