Question

type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
The table shows a proportional relationship between x and y.

x 1 2 3
y 3 6 9

The proportionality constant (y to x) is ____

Answer 1

the proportionality constant is 1/3 meaning y is 1/3 of x or x is 3×y

Answer 2

Answer:

$k=3$

Step-by-step explanation:

1) The Proportionality Constant (k) is given by the following ratio:

$k=\frac{y}{x}=\frac{3}{1}=\frac{6}{2}=\frac{9}{3}\Rightarrow k=3$

This shows that this function is a linear function (with b=0), and proportional one, that can also be written in this form:

$y=kx \: \Rightarrow y=3x$
