Question

Which ordered pair does NOT satisfy the relation 2x-y=divided by 3

a. (-1,1)

b. (-3,-3)

c (0,-3)

d (-2,-1)

Answer 1

(2x-y)/3

a (-2-1/3 = -1

b (-6+3)/3 =-1

c (0+3)/3 = 1

d (-4+1)/3 = -1

while the question is ambiguous, does it read 2x - y = 3 or (2x-y)/3? or 2x -y/3?

just plugging in the values in a through d shows c is the only one that is different, while a,b and d all =-1

that may be a good clue c is the answer you want.
