Do these pairs of values (x and y) represent two quantities that are proportional? X. y 1 1 3 4 8 10 15 18 27 O A. No, because not all of the pairs represent the same ratio. O B. No, because not all of the x-values can be divided by 2 evenly. O C. Yes, because all of the pairs represent the same ratio. O D. Yes, because as x increases, y increases.

Do these pairs of values x and y represent two quantities that are proportional X y 1 1 3 4 8 10 15 18 27 O A No because not all of the pairs represent the same class=

Respuesta :

For a proportional relationship between two variables, x and y, the ratio of y to x must be constant and this constant value is known as the constant of proportionality. Looking at the given table,

3/1 = 3

8/4 = 2

15/10 = 3/2

27/18 = 3/2

All the pairs do not represent the same ratio. this means that there is no constsnt of proportionality. Thus, the correct option is A
