Algebra Lesson 3.4: Graphing Vertical and Horizontal Lines

Practice Exercises:

For each of the following equations, decide whether the graph is a vertical line, horizontal line, or neither

1. \(x = 2\)

2. \(y = x\)

3. \(y= 1\)

Graph each of the following equations

4. \(y=\frac{1}{2}\)

5. \(x = -3\)

Use the following graph two answer Exercises 6 and 7

6. What is the equation of the vertical red line?

7. What is the equation of the horizontal green line?

Review Exercise:

8. Which of the two lines in the graph above is the graph of a function? (Review the vertical line test for functions)
