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

Yup ok so plug in those x values into the equation 2x + 3y = 7

2(-1) + 3y = 7
-2 + 3y = 7
+2 +2

3y = 9
/3 /3


y = 3

So, (-1,3) for the x value of -1

Answer 2

Continue plug in those values and you'll narrow it down :p
