Question

Does y+x=1 show direct variation

Answer 1

No

Explanation:

Equations with direct variation follow the form y= kx, where k = constant of proportionality.

To find out if y + x = 1, we need to isolate y by itself.

Step 1: Subtract x from both sides.

• 
  `y+x-x=1-x`
• 
  `y=-x+1`

As you can see, y + x = 1 does not show direct variation.
