9. The equation y = 3x represents a proportional relationship. What is the constant of proportionality?

The constant of proportionality is 3

Step-by-step explanation:

Given:

y = 3x

The constant of proportionality is 3

y and x are variables respectively

just as writing

y = kx

Where,

k = constant of proportionality

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
