Question

1. Which is the equation of the line?


A.
2x + y = –3

B.
x – 2y = 6

C.
2x – y = 3

D.
x + 2y = –6


2.

Which is the graph of 6x – 2y = 12?

Answer 1

A) The answer is B because if you plug in the two intercepts (0,-3), and (6,0) it is the only equation that works for both.
B) The easiest way is to simplify the equation (6x-2y = 12 => 3x-y=6) and then to plug in the intercepts (0,-6) and (2,0) or check the slope. Either way the answer is A.

Hope this helps!
