The graph below is used to convert between
- temperature in degrees Fahrenheit (F)
and - temperature in degrees Celsius (C).
a) Use the graph to convert 40 degrees Fahrenheit into degrees Celsius.
At one temperature, T,
the number of degrees Celsius is double the number of degrees Fahrenheit.
The graph of C = 2F can be drawn to help find this temperature.
b) On the grid opposite, draw the graph of C = 2F for values of F from –25 to 25
You may use the table to help you.
c) Use your graph to estimate the value of T.
Give your answer in degrees Celsius.
