Answer:
If the given equation is
comparing with [tex]y = kx[/tex]
Therefore, the option [tex]C[/tex] is correct.
Step-by-step explanation:
Given
We know when [tex]y[/tex] varies directly with [tex]x[/tex], means that when x increases, y increases by the same factor
i.e.
y ∝ x
[tex]y = kx[/tex]
where k is the 'constant of proportionality.
[tex]k\:=\:\frac{y}{x}[/tex]
If the given equation is
comparing with [tex]y = kx[/tex]
Therefore, the option [tex]C[/tex] is correct.
