Course description
In this course, you'll understand linear functions by exploring real-world patterns where quantities change at a constant rate. You'll find rates of change from graphs and coordinates, work backward to discover initial values, and calculate the slope of a line based on two points. You'll graph lines with any slope and confidently work with linear relationships in multiple representations.
Topics covered
- Recognizing linear vs. nonlinear relationships
- Finding rates of change from graphs
- Finding the initial value (y-intercept) of a linear function
