An equation which models the relationship between X and Y is
y = 54.5x
The correct answer is option (D) y = 54.5x
"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."
From given data we can observe that,
163.5/3 = 54.5 ...................(1)
327/6 = 54.5 ...................(2)
599.5/11 = 54.5 ...................(3)
From (1), (2) and (3),
y/x = 54.5
⇒ y = (54.5)x
Therefore, an equation which models the relationship between X and Y is y = 54.5x
The correct answer is option (D).
