RHS Mathematics Department Algebra 1 Linear Unit 2012-2013 2 Algebra 1 – Unit 2: Linear Functions Alignment Record HSCE Code Expectation A1.1.1 Give a verbal description of an expression that is presented in symbolic form, write an algebraic expression from a verbal description, and evaluate expressions given values of the variables. A1.2.1

A2.4.1 Write the symbolic forms of linear functions (standard [i.e., Ax + By = C, where B ≠ 0], point-slope, and slope-intercept) given appropriate information and convert between forms. A2.4.2 Graph lines (including those of the form x = h and y = k) given appropriate information.

A3.1.4 Use methods of linear programming to represent and solve simple real-life problems L1.1.2 Explain why the multiplicative inverse of a number has the same sign as the number, while the additive inverse has the opposite sign. L1.1.3

Identify the zeros of a function and their role in solutions to equations. • Identify domain and range in context of a given situation. Understand linear functions have a constant rate of change and be able to identify it graphically, in a table, symbolically and verbally.
