Answer:
x and y do not show direct variation
Step-by-step explanation:
Two quantities x and y show direct variation when
y = kx
and k ≠ 0
Given x = y + 2
Making y the subject of the formula:
y = x - 2
The equation above cannot be written in the form y = kx
This means that x and y are not in a proportional relationship
For instance, let's say when x = 4
y = (4) - 2 = 2
Now, if x is doubled, x = 8
y = (8) - 2 = 6
Therefore, doubling x does not necessarily double y, hence they are not in a direct variation.
