Answer: y = 1/4x

Step-by-step explanation:

If the constant of proportionality is K, then:

y = kr

In which equation do we multiply x by 0.25 to get y?

1/4 = 0.25

The correct answer is y = 1/4x

How to solve the problem?

The problem can be solved by following steps.

  • For the scale function we have an equation y =k*x where k is the constant of proportionality

As We need to find the equation of a constant of proportionality = 0.25

we get y = 0.25

Therefore y = 25/100 =1/4x

Hence the y =1/4x is the equation that has a constant of proportionality equal to 0.25
