1. Is the point (−3, 0) on the x-axis or y-axis? How do you know?
2. Explain in words how you plot the point (4, −2) in a rectangular coordinate system.
3. How do you determine if an ordered pair is a solution to a given equation?
4. Is the point (0, 8) on the x-axis or y-axis? How do you know?
5. What is the difference between the equations of a vertical and a horizontal line?

   1. Find the x- and y- intercepts
   2. Explain what the x- and y- intercepts mean for Ozzie.
7. What does the sign of the slope tell you about a line?
8. Are all horizontal lines parallel? Explain your reasoning.
