Question

What is the constant of proportionality in the equation y=2.5xy=2.5x?

Answer 1

\left[y \right] = \left[ 0\right][y]=[0] totally answer

Answer 2

Constant of proportionality in the given equation is, 2.5

Explanation:

The Direct proportionality says that:

`y \propto x`

then, the equation is of the form : y = kx .....[1] where k is the constant of proportionality.

Given the equation:
`y = 2.5x`

On comparing given equation with [1] we get;

k = 2.5

Therefore, constant of proportionality in the given equation is, 2.5
