A temperature of a body can be measured in Celsius units as or in Fahrenheit unit
as
. The relation between the two systems of measurement of temperature is given
by the linear equation =
9
5
+ 32.
(i) Draw the graph of the linear equation.
(ii) From the linear equation find the temperature of the body in Fahrenheit. If the
temperature of the body is 20.
(iii) If the temperature is 68, then find the temperature in Celsius.
(iv) For what measure, the temperature in Fahrenheit and Celsius will be equal?
(v) Find the value of when = 0.
