Chapter 8 – Functions and Graphing 8.3 – Graphing Linear Equations Using Intercepts

The graph of a linear function may cross either the x -axis, the y -axis, or both axes.

Intercepts
The x -intercept is the x -coordinate of the point where the graph crosses the x -axis.
The y -intercept is the y -coordinate of the point where the graph crosses the y -axis.

Identify the x- and y-intercepts.

The y -intercept and x -intercept can be used to graph a linear equation.
To find the x -intercept, let y = 0 in the equation and solve for x .
To find the y -intercept, let x = 0 in the equation and solve for y .

Find the x -intercept and the y -intercept for each equation. Then graph the equation. x + 2 y = 4 y = 3 x - 6

Some linear equations have just one variable. Their graphs are horizontal or vertical lines.
