Y=-3x+1
So the answer is A. All you're doing is moving the 3x to the opposite side, and because your switching the side, you need to switch the sign. So it's a negative 3x after you solve for y. Solving for y(or any letter) is just getting that letter alone on one side of the equal sign.
Answer:
y=-3
Step-by-step explanation:
there is no slope so x will not be used in the equation it also crosses at -3
