Here again is the histogram showing the distribution of 50 ages at death due to trauma (accidents and homicides) that were observed in a certain hospital during a week.

Table 2 shows a proportional relationship between x and y.

Step-by-step explanation:

We are given four options with table

Table 1:

x    : 0    1     2

y    : 4    8    12

Now we make equation of given table.

This is linear relation not proportional.

Table 2: (TRUE)

x    : 1     2    3

y    : 4    8    12

Now we make equation of given table.

This is a proportional equation. Because y is proportional to x with constant of proportionality 4.

Table 3:

x    : 0    1     2

y    : 0    1    4

Now we make equation of given table.

This is quadratic

Table 4:

x    : 1     2    3

y    : 2    4    8

Now we make equation of given table.

This is exponential function.

Thus, Table 2 shows a proportional relationship between x and y.
