a. A U C = {1,3,4,5,6,12,2,9,10}

b. A ∩ B = {3}

c. A'= {2,7,8,9,10,11}

d. (A ∩ C)' = {2,6,7,8,9,10,11,12}

e. A' ∩ B' = {2,9,10,11}

f. A U C' = {12}

g. (A U B)' ∩ C = {1,3,4,5}

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
