Question

Can you please help this is urgent??!!!!

If y is directly proportional to x, what is the constant of proportionality for the following table?
A. this is not a direct proportion
B. 14
C. 4
D. 2.25

Answer 1

B. 4

Explanation:

A direct proportion has the form

y = kx or k=y/x,

where k is the proportionality constant.

Let's test some points.

Second point

k = 8/2 = 4

Fifth point

k = 23/5.75 = 4

You will get the same result for every point, so the constant of proportionality is 4.
