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

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:

When y = 1, x = 2;

So, we have:

Make k the subject

Hence, the constant of proportionality is 1/2

3; 9 is 8 to -4

step-by-step explanation:

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
