__8.F.A.1 Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. Function notation is not required in Grade 8. 8.F.B.5 Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.__

**Objective:**__: What's the best way to tell the story when given the graph of a function?__

**Essential Question****I Can**explain the story told by the graph of a function.

__8.F.A.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change. 8.F.A.3 Interpret the equation y=mx+bas defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A=s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line. 8.F.B.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.__

**Objective:**__: How does the rate of change and initial value of a graph relate to a function?__

**Essential Question****I Can**explain in my own words how the graph of a linear function relates to its rate of change and initial value. I can determine whether a function is increasing or decreasing based on whether its rate of change is positive or negative.

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.__

**Objective:**__: When is a linear function a good model? How can you tell?__

**Essential Question****I Can**decide when a linear function is a good model for data and when it is not. I can use data points to model a linear function.
