**CORE CONTENT STANDARDS**

8.F.4 Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (*x, y*) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

A.CED.2. Create an equation in two or more variables to represent relationships between quantities; graph equations on coordinate aces with labels and scales.

F.BF.1 Write a function that describes a relationship between two quantities.

G.GPE.5 Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

#### STANDARDS FOR MATHEMATICAL PRACTICE

SMP 2: Reason abstractly and quantitatively

SMP 3: Construct viable arguments and critique the reasoning of others.
