TARGET 15D - LINE GRAPHS

Example: A typical line graph is shown below:

Exercise 1. The table below shows the outside temperature in °C at
certain times on one particular day. Draw a line graph of the results.

The graph should use a scale of 1 cm to 1 hour on the horizontal (x)
axis and 1 cm to 10°C on the vertical (y) axis.

Time Temperature °C Time Temperature °C

6 am 0 4 pm 30
8 am 80 6 pm 20
10 am 70 8 pm 15
12 noon 60 10 pm 10
2 pm 50 12 pm 10

Exercise 2. A class carried out a survey to find out how much weed
was growing near a path. The results are shown below. Draw a line
graph of the results.
