Question

What is the constant of proportionality for the relationship shown in the table? x 2 4 6 8 y 1 2 3 4

Answer 1

Answer:

$k = \frac{1}{2}$

Step-by-step explanation:

Given

x 2 4 6 8

y 1 2 3 4

Required

Determine the constant of proportionality (k)

The relationship between x and y is:

$y = kx$

When y = 1, x = 2;

So, we have:

$1 = k * 2$

$2 * k = 1$

Make k the subject

$k = \frac{1}{2}$

Hence, the constant of proportionality is 1/2
