Create equations in two or more variables

What you'll learn

1. Write an equation in two variables to represent a quantitative relationship between two quantities in a real-world context
2. Identify the dependent and independent variables in a relationship and assign them to appropriate axes
3. Create a graph of a two-variable equation on coordinate axes with appropriate labels and scales
4. Interpret points on the graph as solution pairs (x, y) satisfying the equation, and identify what those points represent in context
5. Write equations in two variables for linear, quadratic, and simple exponential relationships arising from real-world situations
