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

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
