Answer:
-2x - y = 4
Explanation:
Standard Form: Ax + By = k
Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:
y + 1 = -2x - 3
y (-y) + 1 = -2x - 3 (-y)
1 = -2x - 3 - y
1 = -2x - 3 - y
1 (+3) = -2x - 3 (+3) - y
4 = -2x - y
Set the equation so that it looks like the standard form equation given above:
-2x - y = 4 is your answer.
