Given:
Constant of proportionality = 2
To find:
The equation represents a proportional relationship that has a constant of proportionality equal to 2.
Solution:
If y is proportional to x, then the proportional relationship is
[tex]y\propto x[/tex]
The equation of this proportional relationship is
[tex]y=kx[/tex]
where, k is the constant of proportionality.
It is given that, constant of proportionality is equal to 2. So, put k=2 in the above equation.
[tex]y=2x[/tex]
The equation equation is [tex]y=2x[/tex]. Therefore, the correct option is C.
