Question

What is the constant of proportionality in the equation y = 2x?

Answer 1

Answer:

Answer:

2 is the constant of proportionality in the equation y = 2x .

Step-by-step explanation:

Definition of constant of proportionality

When two variables are directly proportional to each others .

Let us assume that u and v .

Than the equation becomes u= kv

Where k is called the constant of proportionality .

Thus in the question x and y are proportional variables .

i.e

y = kx

Where k is called the constant of proportionality .

Compare the equation y = kx  with  y=2x .

Thus

k = 2

Therefore 2 is the constant of proportionality in the equation y = 2x .
