Question

what is a constant proprtionality 2.5

Answer 1

Answer:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form \frac{y}{x}=k

x

y

=k or y=kxy=kx

where

k is the constant of proportionality

In this problem we have

y=2.5xy=2.5x

so

the constant of proportionality k is equal to

k=2.5k=2.5

therefore

the answer is

k=2.5k=2.5

Answer 2

Answer:

2.5

Step-by-step explanation:

First you must state that the relationship is proportional. It is because it goes into the origin.

y = 2.5x

k = 2.5 And 2.5 is the constant of proportionality.
