HELP ME OUT PLEASE!
Which equation shows a proportional relationship between x and y?

Answer:
B
Step-by-step explanation:
y cannot have an additional y intercept value other than 0. If it does as in A, then the results will not give proportional answers.
You might ask "Well what about D? does not having an x value qualify?"
No. The question states that the equation must have an x and y value. So A and C are eliminated because they have y intercepts other than 0. And D goes because it has no x value.
Answer: B y = 4x. y will always be exactly 4 times the value of x.
