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 1.2.3 The student will solve and describe using numbers, symbols, and/or graphs if and where two straight lines intersect.

Assessment Limits:

  • Functions will be of the form: Ax + By = C, Ax + By + C = 0, or y = mx + b.
  • All coefficients will be rational.
  • Vertical lines will be included.
  • Systems of linear functions will include coincident, parallel, or intersecting lines.
  • The majority of these items should be in real-world context.

Skill Statements
1.

Given one or more of the following:

  • a narrative description
  • the graph of two lines
  • equations for two lines

the student will do one or more of the following:

  • determine the system of equations and/or its solution
  • describe the relationship of the points on one line with points on the other line
  • give the meaning of the point of intersection in the context of the problem
  • graph the system, determine the solution and interpret the solution in the context of the problem
  • use slope to recognize the relationship between parallel lines.

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