Linear Function

Jennifer Ledwith

Each linear function has a slope. This article teaches how to use a graph to identify the slope of a line.

Rise over Run

To find the slope, use 2 points. Sometimes, the x- and y-values of the points will contain fractions.

Refer to the graph. Put your finger on (-2½,5). Then trace the path down and over to (3½,-6).

  1. How many units did you move down? 11
  2. How many units did you move over? 6

Rise = -11
Run = 6

Slope = rise/run = -11/6

The slope of the line is -11/6.

How to Determine if the Slope is Positive or Negative

Trace the line from left to right. If the graph moves upward, then the slope is positive. If the graph moves downward, then the slope is negative.

Use the following pages to practice identifying the slope of a line.
