Students match multiple representations of linear equations. Each set has a card with the graph, equation, table, 2 verbal descriptions, slope and y-intercept, and a word problem. There are 5 sets of cards. Print them directly onto 3"x5" index cards. I printed 6 sets, put the students in groups of 3-4, and gave each group a set. Another option would be to print a single set and give each group one card. The groups would look for all the other cards that go with theirs.

Combine standard function types using arithmetic operations. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model.
Write a function that describes a relationship between two quantities.
Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
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.
Interpret the equation 𝘺 = 𝘮𝘹 + 𝘣 as 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.
