Direct VariationInverse VariationNeither21 pointTell whether x and y show direct variation, inverse variation, or neither y = x - 2

Answer 1

Given:

Given the equation y = x - 2

Required: Classify it as direct variation, inverse variation or neither.

Step-by-step explanation:

Two variables x and y show direct variation when they satisfies y = ax or y/x = a, where a is non-zero.

Similarly, two variables x and y show inverse variation when they satisfies y = a/x or xy = a, where a is non-zero.

Here, the equation y = x - 2 is in neither of the form y = ax or y = a/x.

So, y = x - 2 show neither direct nor inverse variation.

Final Answer: y = x - 2 show neither direct nor inverse variation.
