Question

Which point does NOT lie on the graph of the line x + 2y = 9?

A. (1, 4)
B. (2, -1)
C. (3, 3)
D. (5, 2)

Answer 1

b

Explanation:

Answer 2

B

When I get questions like this, I just substitute each ordered pair in. In this case, I thought that B didn't seem that it would fit, but I substituted to make sure, and this is what I got:

1-2=9...

...which obviously can't be true, so I knew that B was the correct answer.

Hope I helped! Sorry if I'm wrong. :)
