Answer:
y=-3x+2
Step-by-step explanation:
as x goes up on y goes down 3
slope is change in y over change in x
-3/1=-3
the y intercept is (0,2) so the y intercept is +2
The answer is probably 2 because if you plug in the numbers you would get
3x-4=-12 divided by -6 = +2.

From there we can see that because x equals both to a and b, it must be that a = b.
The answer is B.
When you set up a ratio of all the corresponding sides, the ratios all equal 2:1
