Teach your students how to graph functions without a calculator. Using a basic y=mx+b format, give some x values in a table, have the students calculate the y value, convert to order pairs (O.P.). Finally, they graph their points and voila! A function is born! Also include is basic translation, reflection, and identification of O.P., and values of b, m, and y from a graph.

CCSS8.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.

CCSS8.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.
