Question

Study the table below. Label the table as proportional or non-proportional. Explain your reasoning.

Answer 1

Proportional

Explanation:

If the function is proportional, it will have the following relationship:

f(x) = kx

Let's look at the first one:

-14 = -7k

k = 2

Now let's see if k=2 is true for the rest:

0 = 2(0) True

10 = 2(5) True

16 = 2(8) True

f(x) = 2x. So this is indeed proportional.
