Question

Draw a graph to represent the following relationship between temperature in degree Celsius and degree
Fahrenheit. [C=5/9(F-32°)]
From the graph, find the value of
a) C when F= 302°
b) F when C = 30°​

Answer 1

0 degrees Celsius is equal to 32 degrees Fahrenheit:

0 °C = 32 °F

The temperature T in degrees Fahrenheit (°F) is equal to the temperature T in degrees Celsius (°C) times 9/5 plus 32:

T(°F) = T(°C) × 9/5 + 32

or

T(°F) = T(°C) × 1.8 + 32

A graph is plotted taking ooC along the Y-axis and ooF along the X-axis. It is a straight line
