Question

Tell whether y - x = 4 show direct variation? PLEASE HELP ME IT IS DUE AT 8AM

Answer 1

No, the equation cannot be written as y = kx

Explanation:

Hello!

You can find out if an equation is a direct variation by checking if there is only a coefficient for x and no other constants when solved for y.

Solve for y

• y - x = 4
• y = x + 4

Since there is a constant added to 4, it is not a direct variation.
