I’m gonna say that the thrid option is from least to greatest. -2.5, -2.3 -1.5, -1, -0.9. This is because the higher the number is as a negative the more negative it is, making it more less than the others. Hope this helps.
They relate because the original constant of proportionality is a unite rate. Then the flipped constant of proportionality would not be a unit rate. It's basically the reciprocal of the original constant of proportionality or K.
Step-by-step explanation:
The given equation is :
x = 6y ...(1)
Here,
x and y are variables and 6 is a constant number
It means,
x and y are related directly to each other i.e.
x ∝ y
or
x = ky .....(2)
Comparing equation (1) and (2)
k = 6
Hence, yes they are in direct proportion and the value of constant of proportionality is 6.
