Question

x 3 9 13 20 y 9 27 39 60 state whether the relationship between the varibles in the table is a direct variation an inverse variation or neither if it is a direct or inverse variation write a function to model it

Answer 1

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. If they are inversely proportional, an increase in the value of one variable would cause a corresponding decrease in the other variable.

Looking at the given values, as x is increasing, y is also increasing. The constant of proportionality is

9/3 = 27/9 = 3

Therefore, the relationship is a direct variation and the function to model it is

y = 3x

Answer 2

The relationship is a direct variation and the function to model it is y = 3x.

Information regarding variables:

• In the case when two variables are directly proportional, so an increase in the value of one variable should be an increase in the other variable.
• And,  on the other side if there is an inversely proportional, an increase in the value of one variable would decrease in the other variable.
