This product will save you time as the guided notes and examples are ready for you to copy and give your students. These activities were created as teacher led lessons in which students stay engaged as they complete the notes and examples in the activities listed below. Independent practice is included in each activity.

Included in this resource:

1. Construct a function to model a linear relationship given in different representations by finding the rate of change and initial value. 10 student pages

2. Interpret the rate of change (slope) and initial value (y-intercept) of functions in different representations according to the situation the function models. 8 student pages

3. Analyze and construct qualitative graphs by describing where the function is increasing, decreasing, linear or nonlinear. Compare different parts of the graph to tell which part has the greatest rate of change. 7 student pages

4. Many Guided Examples

5. Detailed Answer Keys

6. Lots of Independent Practice

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.
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.
