1. Objective: To choose appropriate scales and intervals for graphs.

2. A Grid X-axis and Y-axis Labels Title

3. If in May 550 books were sold instead of 450, what will you have to change in your graph?

4. it’s a series of numbers placed at fixed distances to help label the graph. You use the range of your data to decide on your scale. You start a scale at 0 and end at a number greater than the greatest number in your data. So in this case your scale will be from 0 to ______.

5. W HAT IS THE SCALE OF THIS GRAPH ? What is the interval? (Hint: its related to the scale. )

6. I NTERVAL The interval of a graph is the difference between one number and the next on the scale. What if we change the interval to 10?

7. S CALE AND I NTERVAL
