2: Cho A, B, C là các tập hợp. Chứng minh rằng (a) A∩ (B\C) = (A∩ B)\(A∩ C).
(b) A∪ (B\A) = A∪ B.
(c) A\(A\B) = A∩ B.
(d) (A\B)\C = (A\C)\(B\C).

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
