Place the red dot on the x-intercept and the blue dot on the y-intercept. Then, use the black dot to find a third point on the line.
1. Graph at least 10 different lines. Write the equations and draw the graphs on a separate sheet of graph paper. 2. Create a rule for finding the x and y intercepts from the equation. 3. How would you explain your rule to another student? 4. Why does your rule work?
