Algebra Lesson 3.3: Graphing using Slope-Intercept Form

Practice Exercises:

For each of the following equations, find the slope and the \(y\)-intercept. Then use these to graph the equation.

1. \(y = 4x -1\)

2. \(y = \frac{2}{3} + 3\)

3. \(y = x +4\)

Use the following graph to answer Exercises 4-6

4. Write the equation of the red line in slope-intercept form.

5. Write the equation of the blue line in slope-intercept form.

6. Write the equation of the green line in slope-intercept form.
