Construct a function to model the linear relationship between two variables.

Unpacked Content

Knowledge

Students know:
  • That the rate of change of a function is the ratio of change in the output to the change in the input.
  • how to find the rate of change/slope as well as the initial value/y-intercept.

Skills

Students are able to:
  • Construct the graph of a linear function.
  • Identify the slope and y-intercept of functions in different contexts.

Understanding

Students understand that:
  • Terms such as slope and y-intercept describe a graphical.
  • Representation of a linear function and correlate their meaning to the rate of change and initial value, where the input is 0.
  • Using the units from a context appropriately is needed to make their description of rate of change and initial value accurate.

Vocabulary

  • Function
  • Linear
  • Non-linear
  • Slope
  • y-intercept
