Question

the cost of a toy elephant Is is the same as the cost of 3 balls Express the statement as linear equation in two variables and Plot the equation on a graph paper ​

Answer 1

The linear equation will be x =3y

Explanation:

Given, the cost of toy = cost of 3 balls

Let the cost of elephant be x

The cost of one balls be y

Hence, as per the data given the linear equation will be x=3y

So when

x : 3 6 9 12 15 18 21 24 27.....................

y : 1 2 3 4 5 6 7 8 9........................

One one unit of y x increases 3 units

Thus taking cost of elephant on x axis and the cost of balls n the y axis we can graph the line x = 3y

where

In x axis = 1 unit is equal to cost of one toy elephant

In y axis 1 unit is equal to cost of one ball
