A K Upadhyay and S Upadhyay Solutions for Chapter: Linear Equations in Two Variable, Exercise 1: NCERT Exercises With Solutions

If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as $5$ units. Also read from the graph the work done when the distance travelled by the body is
(i) $2$ units (ii) $0$ unit

In countries like USA and Canada, 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:
$F=\left(\frac{9}{5}\right)C+32$
Draw the graph of the linear equation above using Celsius for x-axis and Fahrenheit for y-axis.

In countries like $USA$ and Canada, 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:
$F=\left(\frac{9}{5}\right)C+32$
