the table describes the coordinates of several points on a graph. they form a proportion.

what characteristic of the values in the table shows that they form a proportion?
a. both columns include both positive and negative numbers.
b. the numbers in the x column increase by a constant amount.
c. each number in the x column relates to only one number in the y column.
d. every number in the x column can be multiplied by the same value to get the number in the y column.

Step-by-step explanation:

A proportion is the equivalence betweent two rations.

In this case, if the table shows a proportion between variables, they must have a constant ratio of change. In other words, both variables must have a ratio that is constant to each pair. To know if such constant ratio exists, we just have to divide.

However, it's easier if we multiply a factor to x-values to obtain y-values. You can observe that if we multiply with each x-values, we will obtain each y-value pair.

You can see that if we multiply the same number, we obtain the y-column, that meanst 1/2 is the ratio that relates this variable.

Therefore, the right answer is D.

When we have to variables related by a specific proportion, one of them can increase by a constant amount, but that not necessarily ensure that there is a proportion. It must exist a constant ratio to call that a proportion.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

ian gonna lie that is way to much
