Question 8 In countries like 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: F=95C+32 (i) Draw the graph of the linear equation above using Celsius for x-axis and Fahrenheit for the y-axis. (ii) If the temperature is 30∘C, what is the temperature in Fahrenheit? (iii) If the temperature is 95∘F, what is the temperature in Celsius? (iv) If the temperature is 0∘C, what is the temperature in Fahrenheit and if the temperature is 0∘F, what is the temperature in Celsius? (v) Is there a temperature which is numerically the same in both Fahrenheit and Celsius? If yes, find it.
