Intercepts are an important part of graphs; they can tell us a lot about our data. For example, y-intercepts often tell us our starting amount. Here are some vocabulary words to help you with this lesson:

- X-intercept = where the graph crosses the x-axis, and where \(y = 0\)
- Y-intercept = where the graph crosses the y-axis, and where \(x = 0\)
