WILL MARK BRAINLEST This table shows a proportional relationship. x −4 −2 0 2 4
y −14 −7 0 7 14
Which ordered pair could also belong to this relationship?
A. (−6, 21) C. (−1, −3)
B. (1, 3) D (6, 2)

D (6, 21)

Step-by-step explanation:

Since the ratio of the corresponding values of x and y given in the table is 2 : 7

So, 6/ 21 = 2/7 = 2: 7

Thus, D (6, 21) is the correct answer.

b

step-by-step explanation:

the word superfluous means unnecessary

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
