8.(i) In countries like the USA and Canada, the temperature is measured in Fahrenheit, whereas in countries like India, it is measured in Celsius. Here is a linear equation that converts Fahrenheit to Celsius:
(i) Draw the graph of the linear equation above using Celsius for x-axis and Fahrenheit for the y-axis.
Let celsius be on x-axis and Fahrenheit be on y-axis.
Putting x=0, we get
Putting x=5, we get
Putting x=10, we get
Hence, points are (0,32) , (5,41) and (10,50).
