Q4 of 58 Page 44

Let us express the following statements into linear equations in two variable and draw the graph of the equations.

At present the age of Sujata’s father is more than the age of Sujata by 26 years, [Let us suppose Sujata’s father’s age is x years and Sujata’s age is y years.]

Let Sujata’s age is x years and her father’s age is y years.


Given, At present day Sujata’s father’s age is 26 years more than her.


y = x + 26


Putting different values of x, we get different values of ‘y’, hence we get points for plotting as:
