Answer:
-1/2 and 2
Step-by-step explanation:
Since you need y=mx+b you have to convert your equation to match this
So, 3x+6y=12
Subtract 3x from both sides to get the y term on the left side alone.
This leaves 6y=-3x+12
From there divide 6 from both sides to give you your y term alone on the left side completely.
That leaves you with y=-1/2x+2
Meaning your M=-1/2 and your B=2
Your graph then should have the start point be at y=2 from there move -1 spaces down the y axis, and go to spaces to the right. Making your line move between r and n
