15. Which of the following is true about the relationship in the table shown? Х 7 11 20 25 100 8.4 13.2 24 30 120 A. The table is non-proportional because it does not include the point (0,0). B. The table is non-proportional because the x-values do not increase at a constant interval. C. The table is proportional because all of the x and y-values are positive and increasing, D. The table is proportional because the ratio between y and x is constant.

Explanation:

To determine if the table is proportional or not, we need to find the ratio between x and y for each of the data. if it is constant, then it is proportional

Proportional relationship:

y = kx

k = constant of proportionality

k = y/x

for the x = 7, y = 8.4

k = 8.4/7 = 1.2

for x = 11, y = 13.2

k = 13.2/11 = 1.2

for x = 20, y = 24

k = 24/20 = 1.2

for x = 25, y = 30

k = 30/25

k = 1.2

when x = 100, y = 120

k = 120/100

k = 1.2

Since the ratio between y and x is the same for all, the table is proportional

The correct option:
