2-3: The Slope of a Line

Part 1

Intro

Slope describes the steepness of lines in the coordinate plane. The slope of a line is the ratio of the vertical change to the horizontal change.

A graph.

The slope of the line is 3 halves .

Example Identifying Slopes from Graphs

Find the slope of each line.

  • a. A graph of a line passing through the points (0, 0) and (3, 2).

  • b. A graph of a line passing through the points (-2, -2) and (3, 1).

  • c. A graph of a line passing through the points (1, -2) and (5, -3).
