Does the equation 3y =4x represent a direct variation? If so, state the value of k.

Sagot :

To solve this question, we need to find the value of k. We can obtain this value as follows:

[tex]3y=4x\Rightarrow y=\frac{4}{3}x\Rightarrow\frac{y}{x}=\frac{4}{3}[/tex]

Then, the direct variation, k, is equal to 4/3, so that:

[tex]y=\frac{4}{3}x[/tex]

k = 4/3
