Which is a direct variation equation? 1. Y=x+5
2. Y=-5/x
3. Y=-5x
4. Y=x-5

Help

3. y = -5x

Step-by-step explanation:

In a direct variation equation, the constant of proportionality (k) is a direct coefficient of the variable x.

Y will be set equal to x multiplied by this coefficient.

Since y = -5x directly relates x to y, with the constant of proportionality, it is a direct variation equation.

So, 3. y = -5x is the correct answer.

its b

step-by-step explanation:

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
