Answer:
6 = -3x -y
Explanation:
Standard form. is Ax + By = C
So let's just move some parts of the equation around to match this form.
First move y to the other side of the equation by subtracting y from both sides.
y=-3x-6
y - y = -3x -6 - y
0 = -3x -6 - y
Now move the 6 to the other side of the equation by adding 6 to both sides.
6 = -3x - 6 - y + 6
6 = -3x -y
You can check your work by graphing 6 = -3x -y and also y=-3x-6 to see that it's the same exact line.
