Which relationship between x and y in the equation shows a proportional relationship?

A: y + 5 = x + 3

B: y = 5 (x + 3)

C: y= 5x + 3

D: y=3x

You guys are smarter than me,

Respuesta :

to be proportional means to exist a number as a result of a raport between two numbers
the correct answer is d because y/x=3
from the other choices you cannot find a raport between y and x
