To plot points on a coordinate plane that represent the relationship between the independent and dependent variables.

Front

What is a table of values?

Back

A table that shows pairs of input (x) and output (y) values for a function.

Front

What is the slope of a line?

Back

The rate at which y changes for a change in x, often represented as 'm' in the equation y = mx + b.
