Question

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

Answer 1

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

`3y=4x\Rightarrow y=(4)/(3)x\Rightarrow(y)/(x)=(4)/(3)`

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

`y=(4)/(3)x`

k = 4/3
