Question

How do you write the direct variation equation if y = 8 when x = 24?

Answer 1

`y=1/3x`

Explanation:

If `y` is directly proportional to `x` with some constant `k`, the equation is represented as:

`y=kx`

So here, we get:

`8=k*24`

`8=24k`

`k=8/24=1/3`

Therefore, the equation is:

`y=1/3x`
