Now it's time to practice graphing lines given the slope-intercept equation. Graph at least five new problems.

Graphing the line y = mx + b

When you are finished graphing at least five new problems, move on to the next section.

Instructions:

  1. Move A or B to the y-intercept.
  2. Move the line to show the proper slope.
  3. "You did it!" will appear if it is correct.
  4. Click on "New Line" and repeat.
