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

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
