Question

type the correct answer in the box. use numerals instead of words.

what is the constant of proportionality in this graph of an inverse variation function?

\\(k = \\)

Explanation:

Identify a point on the graph

$$ (x, y) = (2, 4) $$

Apply the inverse variation formula

$$ y = \frac{k}{x} \implies k = x \cdot y $$

Calculate the constant of proportionality

$$ k = 2 \cdot 4 = 8 $$
