Interpreting graphs in an unfamiliar context

Interpreting graphs in an unfamiliar context.

  • Check axis labels and scales before reading values.
  • Use key points and the correct curve shape. Join a curved graph smoothly.
  • An asymptote is approached; do not join separate branches across it.

Example 1

The graph shows the volume of water in a tank. Read the initial volume and the volume after 2 minutes.

Coordinate graph0.511.522.533.5424681012140
Read where the graph meets the vertical axis.Move up from the chosen time, then across to the volume axis.
Initially 2 litres; after 2 minutes, 8 litres.

Example 2

The graph shows the volume of water in a tank. Read the initial volume and the volume after 3 minutes.

Coordinate graph123452.557.51012.5150
Read where the graph meets the vertical axis.Move up from the chosen time, then across to the volume axis.
Initially 2 litres; after 3 minutes, 11 litres.
