Question

Find the solution set for 6x – 2y = 8, given the replacement set {(-2, -10), (-1, -7), (1, -2), (2, 0)}.
Answer

{(-2, -10), (-1, -7), (2, 0)}

{(-2, -10), (-1, -7), (1, -2)}

{(-2, -10), (-1, -7)}

{(2, 0)}

Answer 1

basically, you want to test each pair of x and y values. First, test (2,0) ... doesn't work.
so A and D are out.
test (1,-2)...doesn't work. so C is out, too. that leaves B as the right answer.
