Proportional or nonproportional? (in graph)

Nonproportional

Step-by-step explanation:

If the answer is Proportional, the change in x to y will be constant throughout the chart.

However, note the change.

-9 + 26 = 17

-6 + 16 = 10

0 - 4 = -4

3 - 14 = -11

15 - 54 = -39

The numbers vary, which means they are not proportional.

i am sorry

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
