Graphing Linear Equations Using Intercepts

2. What you will learn! How to find the x- and y-intercepts of graphs.
How to graph linear equations using the x- and y-intercepts.

3. Vocabulary
x-intercept
y-intercept

4. What you really need to know!
The x-intercept is the x-coordinate of a point where a graph crosses the x-axis. The y-coordinate of this point is 0.
To find the x-intercept, let y = 0 and solve for x.

5. What you really need to know!
The y-intercept is the y-coordinate of a point where a graph crosses the y-axis. The x-coordinate of this point is 0.
To find the y-intercept, let x = 0 and solve for y.

6. State the x-intercept and y-intercept of the line.
Example 1:
State the x-intercept and y-intercept of the line.
x-intercept -2
y-intercept -2

7. State the x-intercept and y-intercept of the line.
Example 2:
State the x-intercept and y-intercept of the line.
x-intercept None
y-intercept 2
