Question

Consider the following table. Is the relationship proportional? Explain your answer.

x y
-2 -27
1 12
4 57
10 147

Answer 1

Not proportional there is no pattern and one of the point is negative and the rest is positive so it makes no sense

Answer 2

Not proportional.

I looked at the following ordered pairs:

(-2,-27)

(1,12)

(4,57)

(10,147)

Please see I have the points correct.

Thank you kindly.

Explanation:

To see if it is proportional, we just need to see if the following equality holds:

`(-27)/(-2)=(12)/(1)=(57)/(4)=(147)/(10)`?

I'm going to put each fraction into my calculator.

`13.5=12=14.25=14.7` which is totally not true so this relationship is not proportional.
