This document discusses how to graph linear equations using intercepts. It explains that the x-intercept is the x-coordinate where the graph crosses the x-axis and the y-intercept is the y-coordinate where the graph crosses the y-axis. To find the intercepts, set either x or y equal to 0 in the equation and solve for the other variable. Using the intercepts, linear equations can be graphed by plotting the points where they cross the axes.

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

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

4. Identify the x- and y-intercepts.

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

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