Question

What is the constant of proportionality in the equation y=\dfrac54xy= 4 5 ​ xy, equals, start fraction, 5, divided by, 4, end fraction, x?

Answer 1

Answer:

$\frac{5}{4}$

Step-by-step explanation:

We have been given an equation $y=\frac{5}{4}x$ and we are asked to find the constant of proportionality in the given equation.

If two variables are proportional, there is always a constant ratio between them. This constant is called the constant of proportionality.    

Since we know that a directly proportional equation in in form: $y=kx$, where k is constant of proportionality.

Upon comparing our given equation with the directly proportional equation we can see that $k=\frac{5}{4}$, therefore, constant of proportionality in our given equation is $\frac{5}{4}$.

Answer 2

Answer: it’s 1/2

Step-by-step explanation:

If the constant of proportionality is

k, then Y = kx

idk if that made sense, but I hope this helps
