To find the relationship between the variables in given case is direct variation, an inverse variation, or nether. Also to determine the equation.
The equation is
Given information:
The table is:
3 | 15 |
8 | 40 |
10 | 50 |
22 | 110 |
Concept:
Inverse variation: When one of the given variables increases with decrease in other variable, then it is inverse variation or vice versa.
It can be represented as:
Direct variation: When one variable increases with increase in other variable, or decreases with decrease in other variable then it is direct variation.
It can be represented as:
Calculation:
From the given table:
As ratio is constant, it is direct variation.
Equation shall be given by,
As the value of constant is
Conclusion:
Hence, the equation is
