Which table shows a proportional relationship between x and y? a. x y 2 4 3 6 4 9 b. x y 3 4 9 16 15 20 c. x y 4 12 5 15 6 18 d. x y 1 4 2 8 3 15

C.

Step-by-step explanation:

The relationship is proportion if y/x is constant.

So it is C because 12/4 = 15/5 = 18/6 = 3.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
