Question

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

Answer 1

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

2.5

Answer 2

Answer: 2.5

Step-by-step explanation:

We know that the constant of proportionality is the ratio between two directly proportional quantities.

The equation of direct variation between two quantities x and y is given by :-

$y=kx$, where k is the constant of proportionality,

The given equation : - $y =2.5xy$

When we compare to the general direct variation equation , we get

$k=2.5$

hence, the constant of proportionality in the equation  2.5
