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

Answer:

Constant of proportionality in the given equation is, 2.5

Step-by-step 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
