Question

Answer ASAP, 100 points and brainiest for the correct answer

What is the constant of proportionality?

Answer 1

First try dividing the y values by the x values to see if they re all the same. If they are that would be the constant. If not we would need to look at other formulas.

4/1 = 4

8/2 = 4

12/3 = 4

16/4 = 4

Since they all equal 4, the constant of proportionality is 4.

Answer 2

Answer:

$y=4x$

Step-by-step explanation:

$k=\frac{y}{x}=\frac{8}{2} =4$
