Answer:

y=2x+1

Explanation:

Well, let's start with the graph given by the question. (Picture 1 below)

1) We can pick two points, (1,1) and (-1,-3), also for the slope we can see it's a positive one so m >0

2)
$m=(-3-1)/(-1-1) \\ m=(-4)/(-2)\\ m=2$

So now

y=mx+b

y=2x+b

Plugging in those values (1,1) and (-1,-3)

1=2(1)+b

b=-1

So y=2x-1, instead of 3y=2x+4
