Can someone help me please?
Which of the following equations represents a proportional relationship?
Choose all that apply.
A. 1/3 x
B. y= 3.4x
C. y+1=2x
D. y=2x
I think its A,C,&D.
question mark
@This guy, that didnt age well......
I am from mother russia
Y=3.4x
Lol
all proportions are of the form y=kx
C does not qualify, since it has that extra 1 messing up the proportion.
B does work, though.
It aged like milk
To determine if an equation represents a proportional relationship, we need to check if it can be written in the form y = kx, where k is a constant.
A. Equation A is 1/3 x. This equation is not in the form y = kx, so it does not represent a proportional relationship.
B. Equation B is y = 3.4x. This equation is in the form y = kx, where k = 3.4. So, equation B represents a proportional relationship.
C. Equation C is y + 1 = 2x. This equation is not in the form y = kx, so it does not represent a proportional relationship.
D. Equation D is y = 2x. This equation is in the form y = kx, where k = 2. So, equation D represents a proportional relationship.
Therefore, the equations that represent a proportional relationship are B and D. The answer is B, and D.
