Question

Solve the equation, using the domain of x = {-1, 0, 2}.
2x + 3y = 7

A.{(-1, 3), (0, 7/3), (2, 1)}
B.{(3, -1), (7/3, 0), (1, 2)}
C.{(5, -1), (7/2, 0), (2, 1)}
D.{(-1, -3), (0, 7/3), (2, 1)}

Answer 1

plug in those values for x and see what you get for y. We know right away that B and C are wrong because their x values do not match the domain given
