Two examples
Example 1
Made-up numbers, for practice.
According to the graph, what was the temperature of the water at 20 minutes?- Read the title, then the labels on both axes. The x-axis, along the bottom, is time in minutes. The y-axis, up the side, is temperature in °C.
- Find 20 on the x-axis.
- Go straight up from 20 until you reach the line.
- From that point, go straight across to the y-axis. The point is on the line marked 40.
Answer: 40 °C
Example 2
Made-up numbers, for practice.
According to the graph, at what time was the temperature of the water 30 °C?- This time the temperature is given and the time is asked. You start on the other axis.
- Find 30 on the y-axis, up the side.
- Go straight across until you reach the line.
- From that point, go straight down to the x-axis: 30 minutes.
- The answer is a time, so it comes from the x-axis.
Answer: 30 minutes
