Think about how much money you could make if you were working at a job. You could graph your earnings on the vertical axis, and your earnings on the horizontal axis. You would have a graph where your total earnings were increasing over time. What would the graph look like if your hourly rate was higher? What if it was lower?
When you graph a line, you can think about how it looks. It may be increasing to the right, decreasing to the right, or staying constant/flat.
Today, we will be looking at how the steepness of the line can be assigned a number.
