Answer:
A and B has the same constant of proportionality
Step-by-step explanation:
Where k is the constant of proportionality
We are supposed to find Which relationships have the same constant of proportionality between y and x as in the equation
On comparing with 1
A)6y = 3x
So, this equation has the same constant of proportionality
B)
To find the equation :
Formula :
So,
So, this equation has the same constant of proportionality
C)
To find the equation :
Formula :
So,
So, this equation do not has the same constant of proportionality
D)
To find the equation :
Formula :
So,
So, this equation do not has the same constant of proportionality
Hence A and B has the same constant of proportionality
