CSEC Mathematics · May/June 2008 · Paper 2 · Question 6(a)

The table shown below gives the population in millions of a country in five-year periods from 1980 to 2005.

Using a scale of 4 cm to represent one million persons on the vertical axis and 2 cm to represent five years on the horizontal axis, draw a line-graph to represent the population from 1980 to 2005. Start your horizontal scale at 1980.

This question uses a figure or table from the paper — you'll see it when you practise.
