Question

The quantities x and y are proportional.



Find the constant of proportionality (r) in the equation y = rx


r = __

Answer 1

Answer:

r=3

when we divide these all then,

the proportional is 1/3 so,

x=1

y=3

so the correct answer is 3

Answer 2

Answer:

r=3 is a correct answer.

Step-by-step explanation:

For this , we can plug in pair of x and y and solve for r.

y=rx | plug in Pair

54=r*18| dividing both side by 18

r=3

so r=3 is a correct answer.
