The constant of variation is 1/3 and when x = 3/4, y = 1/4
Two variables are proportional to each other if as one variable increase or decrease, the other variable does the same.
Given that y and x have a constant variation, hence:
y ∝ x
y = kx;
where k is the constant of variation
y=2 when x=6;
2 = 6k
k = 1/3
y = (1/3)x
When x = 3/4;
y = (1/3)(3/4)
y = 1/4
Hence the constant of variation is 1/3 and when x = 3/4, y = 1/4
