Answer:
<h2>D. The product xy is not constant, so the relationship is not an inverse variation.</h2>
Step-by-step explanation:
If the relationship is inverse variation, then the product xy is constant.
2 · 409 = 818
3 · 240 = 720
4 · 194 = 776
The product xy is not constant.
If AB is the hypotenuse, we have to draw the legs of the triangle and see where they intersect. There are two different possibilities (see the picture attached below). Therefore, the answers are (-3,3) and (-8,-4).
