MA19.8A.14

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. [Algebra I with Probability, 12]

Unpacked Content

Knowledge

Students know:
  • When the situation presented in a contextual problem is most accurately modeled by a linear, quadratic, exponential, absolute value or linear piecewise function.
  • How to graph equations on a coordinate plane.

Skills

Students are able to:
  • Write equations with two or more variables.
  • Graph equations on a coordinate plane with appropriate scales and labels.
  • Make predictions based on the graph.

Understanding

Students understand that:
  • There are relationships among features of a contextual problem, a created mathematical model for that problem, and a graph of that relationship.
  • Models can be used to make predictions.

Vocabulary

  • Linear
  • Quadratic
  • Exponential
