It can be y=ox which means y varies directly as x or y is directly proportional as x where I is constant in the equation

Example: y is directly proportional to x when x= 15 y=30

If [tex]y[/tex] varies directly with [tex]x[/tex], then their ratio is constant:

[tex]\dfrac{y}{x}=k[/tex]

So, we can write

[tex]y=kx[/tex]
