Review

• A linear equation is written as y = mx + b. The variable b represents the y-intercept of
the graph of the line. The variable m represents the slope of the line.
• Slope is the steepness of a line. It is calculated as the amount of rise (change in height)
per amount of run (horizontal change).
• Slope can be counted on a graph or calculated from any two points on the line.
