What is constant of Proportionality in the equation y = 2.5x

k = 2.5

Step-by-step explanation:

Compare y = 2.5x to y = kx (which is the equation for direct proportion):

k = 2.5 is the const. of prop.

constant of proportionality = 2.5

Step-by-step explanation:

Given : y = 2.5x.

To find : What is constant of Proportionality in the equation.

Solution : We have given

y = 2.5x.

On comparing with equation of proportionality : y = kx,

Where, k is the constant of proportionality.

On comparing y = 2.5 x by y = kx.

We get k = 2.5

So, constant of proportionality = 2.5

Therefore, constant of proportionality = 2.5
