Mathematics (2019) Grade(s): 09-12 - Algebra I with Probability

MA19.A1.12

Create equations in two or more variables to represent relationships between quantities in context; graph equations on coordinate axes with labels and scales and use them to make predictions. Limit to contexts arising from linear, quadratic, exponential, absolute value, and linear piecewise functions.
