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

Answer:

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.

Step-by-step explanation:

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

$\frac{-27}{-2}=\frac{12}{1}=\frac{57}{4}=\frac{147}{10}$ ?

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.

Step-by-step explanation:

$\frac{4}{5} = 64 \\ \frac{1}{5} = 64 \div 4 \\ \: \: \: \: \: \: = 16 \\ total \: managers \: = 16 \times 5 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 80 \\ number \: of \: male \: \: managers \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{5}{5} - \frac{4}{5} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{5} = 16$
