This topic is in the 'Linear Functions and Graphing' section. There are a lot of ways of thinking about linear functions and one of the most powerful methods is visualizing these functions as lines. It's kind of cool how math symbols on a page turn into graphs that we can interpret, and sometimes you can solve problems just by thinking about the graph, and forgetting about any specific math steps or rules. In this section you'll see a bunch of tutorials focused on the tools that you can use to visualize linear functions graphically. You'll learn about rate of change, or slope, and see how we can write linear functions in different forms.
