Answer:
No
Step-by-step 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.
- [tex]y+x-x=1-x[/tex]
- [tex]y=-x+1[/tex]
As you can see, y + x = 1 does not show direct variation.
