Question

The equation below describes a proportional relationship between x and y. What is the constant of? proportionality? y equals three sevenths x

Answer 1

Answer:

The given equation is

          y =$\frac{3}{7}$ x

→ $\frac{y}{x} = \frac{3}{7}$

reciprocating both sides, we get

→ $\frac{x}{y} = \frac{7}{3}$ ............(1)  

→ Here x and y are Directly proportional to each other.

which means ,

→ x =  k y , where k is constant of proportionality.

Or , $\frac{x}{y}$ = k  ............................(2)

Equating (1) and (2),

k = $\frac {7}{3}$
