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 P
lot the equation on a graph paper 
1 answer:
Answer:
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
