b. (0,0), (1, -1), (2,-2), and (4, -4)
c. (0, -1), (1,0), (2,1), (3,2), and (4,3)
d. (0,0), (1,1), (2,8), (3, 27), and (4, 64)

step-by-step explanation:

this is not a question

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
