Two proportional relationships are given: Relationship A has the equation $y = 0.75x$ and Relationship B passes through the points $(4, 6)$ and $(8, 12)$ . Which statement is true?

Relationship A has a greater constant of proportionality than Relationship B
Relationship B has a greater constant of proportionality than Relationship A (correct answer)
Both relationships have the same constant of proportionality of 0.75
Both relationships have the same constant of proportionality of 1.5

Explanation: Relationship A has $k = 0.75$ . For Relationship B, using either point: $k = \frac{6}{4} = 1.5$ or $k = \frac{12}{8} = 1.5$ . Since $1.5 > 0.75$ , Relationship B has the greater constant. Choice A reverses the comparison. Choice C incorrectly calculates Relationship B's constant as 0.75. Choice D correctly identifies Relationship B's constant but incorrectly states they're equal.
