What's the answer to this question 3x + 2y = -4 and how did you get it

1 answer:

6 0

First you subtract 3x because you are trying to get x alone so subtract 3x on both side so you would get 2y=-3x-4 and then divide the whole thing by 2 so you would get y=-3-4/2 and then you simplify and get y=-7/2 so y=-7/2 is your answer.

Answer: Choice C

(4, 18)

=========================================

Explanation:

One point shown on the graph is (2,9)

If we double each x and y coordinate, then

2*2 = 4
9*2 = 18

We go from (2,9) to (4,18)

Plotting this point on the graph will be on the same line as the other points.

Or you could note that y/x = 9/2 = 18/4 = 4.5
