1. Describing Graphs

2. Distance increases as the speed increases
The pattern appears to be a straight line

3. Height increases as the Age increases
The pattern is not a straight line
The amount of increase gets less as Age increases

4. Generally, temperature decreases with time
From t = 0 to 6 s, temp decreases rapidly.
From t = 6 to 16, temp is steady at 550C
From t = 16 to 26, the temp decreases steadily, but not as fast as at the start

5. Resistance decreases as the temperature increases
The pattern is not a straight line
The decrease is less as the temp increases

6. There is no pattern shown in this graph.
Test results do not appear to be dependent on height

7. Name the equipment
