Attaching answer for 1 below!!
2. C. -- y=2x+9
3. B. -- y=5/3x+3
Step-by-step explanation:
1. First screenshot below
2. To convert standard equations (Ax+By=C) to slope intercept (y=mx+b), what you do is preform inverse operations on A to both sides (modeled below). Then, the equation will look like this; By= -Ax+C. The last thing you need to do to cancel out B from the y is divide both sides by B, and you'll have your answer. So, I did that exact process with the equation and that's how I got C. Now, when you have no number next to the y, you don't need to divide, so it's a very simple process that way.
-2x+y=9
+2 +2
3. Same process for 2, except this time we divided by 3.
