Skill Statements: The Skill Statement gives the reader direction on how an assessment item is written. The Skill Statement describes what information may be given and/or the format of that information. In addition, the Skill Statement describes how the student is expected to respond to the item.

Goal 1 Functions and Algebra

Expectation 1.2 The student will model and interpret real-world situations using the language of mathematics and appropriate technology.

Indicator 1.2.1 The student will determine the equation for a line, solve linear equations, and/or describe the solutions using numbers, symbols, and/or graphs.

Assessment Limits:

  • Functions are to have no more than two variables with rational coefficients.
  • Linear equations will be given in the form: Ax + By = C, Ax + By + C = 0, or y = mx + b.
  • Vertical lines are included.
  • The majority of these items should be in real-world context.

Skill Statements
1.

Given one or more of the following:

  • the graph of a line
  • written description of a situation that can be modeled by a linear function
  • two or more collinear points
  • a point and slope

the student will do one or more of the following:

  • write the equation
  • solve a one-variable equation for the unknown
  • solve a two-variable equation for one of the variables
  • graph the resulting equation
  • interpret the solution in light of the context
  • evaluate the equation for a given value
  • create a table of values
  • find and/or interpret the slope (rate of change) and/or intercepts in relation to the context.

Any correct form of a linear equation will be acceptable as a response.
