Question

Y and x vary directly. If the constant of variation is 4 , what will be the equation for this relationship?

Answer 1

The equation for this relationship will be y = 4x.

Explanation:

Our task is to find the equation.

We know that y and x vary directly. Direct variation implies multiplication, hence:

`\sf{y = kx}`, where k = constant of variation

Since k = 4, we have :

`\sf{y=4x}`

Answer 2

Explanation:

When two variables, y and x, vary directly, their relationship can be represented by the equation:

y=kx

Where:

y is the dependent variable

x is the independent variable

k is the constant of variation (also known as the constant of proportionality)

Given that the constant of variation is 4, the equation for the direct variation relationship between

y and x would be:

y=4x
