In countries like

(i) For graph, we’ll first make the table of solutions by putting some random values of x and thereafter we’ll find corresponding values of y and then we’ll plot these points on graph, join them and extend them in straight line to find the graph.

(Note: ∵ equation is linear graph will always be straight line.)

Table of solutions for the given equation-

GRAPH:

(ii) If the temperature is 30°C, then from the graph, the temperature in Fahrenheit is 86° F. (pt. E)

(iii) If the temperature is 30°C, what is the temperature in Fahrenheit is 35° C. (pt. F)

(iv) Yes.

The temperature that has numerically the same value in both Fahrenheit and Celsius is -40 (pt. G)
