2. 1- A trend over time (upward trend, downward trend or stable trend).trend 2- The size of the changes between data points. For example when did the greatest change occur? 3- What we can predict or estimate. 1- A trend over time (upward trend, downward trend or stable trend).trend 2- The size of the changes between data points. For example when did the greatest change occur? 3- What we can predict or estimate. When interpreting a line graph the reader is usually looking for:

3. Trend Upward trend: there has been a steady/sudden/dramatic increase. Downward trend: there has been a steady.....decrease. 1. Upward trend Downward trend Pattern The general direction that a group of points seem to be heading

4. Upward trend downward trend Back

5. 2. The size of the changes between data points. For example when did the greatest change occur? When was the heart rate at highest level? When was the heart rate at highest level? When was the growth rate fastest?

6. 3- What we can predict or estimate. Estimate the height of the plant after 6 weeks?

7. Extracting and reading data form line graphs
