Example 1

easy
The table shows the temperature at noon each day for five days: Monday 12°C, Tuesday 14°C, Wednesday 11°C, Thursday 15°C, Friday 13°C. Describe how you would draw a line graph to display this data.

Solution

  1. 1
    Step 1: Draw the horizontal axis (x-axis) and label it with the days of the week: Mon, Tue, Wed, Thu, Fri.
  2. 2
    Step 2: Draw the vertical axis (y-axis) and label it 'Temperature (°C)'. Choose a scale from 10°C to 16°C with intervals of 1°C.
  3. 3
    Step 3: Plot each data point at the correct position — (Mon, 12), (Tue, 14), (Wed, 11), (Thu, 15), (Fri, 13).
  4. 4
    Step 4: Connect the points with straight line segments from left to right to show the trend over time.

Answer

A line graph with days on the x-axis and temperature on the y-axis, with points at (Mon,12), (Tue,14), (Wed,11), (Thu,15), (Fri,13) connected by line segments.
Line graphs are used to display data that changes over time. The horizontal axis shows the time intervals and the vertical axis shows the measured quantity. Connecting the points with lines helps visualise trends and patterns.

About Line Graph

A line graph is a chart that uses points connected by straight line segments to show how a quantity changes over time or across a continuous variable. The horizontal axis typically represents time, and the vertical axis represents the measured value.
