Answer:
Neither, why... for it to be direct or inverse variation, the model has to fit either y=k/x or y=kx, it may not have a y-intercept at all if it is inverse variation and it must have a y-intercept of 0 for it to be direct variation.
Step-by-step explanation:
The statement y=2 is quite specific. Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases. yx is a constant number -8. The constant of variation, k , is 23 . Inverse Variation
An inverse variation can be represented by the equation xy=k or y=kx .
That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 .
Suppose y varies inversely as x such that xy=3 or y=3x . That graph of this equation shown.

Answer:
<h2>C. None of the above</h2>
Step-by-step explanation:
Wait, do you want me to solve for x or for y??
For y it's,
For x it's,
Answer:
22/5
Step-by-step explanation:
The sides increase but in the same ratio,
Hence opposite/adjacent for image and pre image is the same ratio.
Therefore, tanX is 22/5
