Answer:
The answer is below
Explanation:
The question is not very clear but i would try to answer it
Given that [tex]y=\frac{1}{2}x[/tex]
The constant of proportionality is the ratio between quantities that are directly proportional to each other. In this case, the constant of proportionality is the ratio of y to x.
[tex]Since\ y=\frac{1}{2}x\\we\ have\ to \ find\ the\ ratio\ of\ y \ to \ x\\\frac{y}{x} =\frac{1}{2}[/tex]
Therefore the constant of proportionality is 1/2
A) For 6y = 3x
Dividing through by 6x gives:
[tex]\frac{6y}{6x}=\frac{3x}{6x}\\ \\\frac{y}{x}=\frac{1}{2}[/tex]
They have the same constant of proportionality
The remaining options are not clear
