I know that you just multiply all of the number by 1/3 but how do I do the rest?​

Answer:

  • Constant of proportionality: 1/3
  • Equation: y = 1/3x

Explanation:

You want the constant of proportionality and the equation associated with a table showing y-values are 1/3 of x-values.

Constant of proportionality

The equation describing a proportional relation can be written ...

y = kx

where k is called "the constant of proportionality."

This equation means that a value for y is found by multiplying the x-value by that constant.

Since you already know that y-values are found by multiplying x-values by 1/3, you already know that k = 1/3, and ...

the constant of proportionality is 1/3

Putting that value in the equation gives you ...

equation: y = 1/3x
