What would be the equation - 2x+y+3=0 in y=mx+b form?

The answer is y = 2x - 3.

Step-by-step explanation:

Move 2x to the right side of the equation by adding it to both sides:

-2x + y + 3 = 0

+ 2x + 2x

y + 3 = 2x

Then, move 3 to the right side of the equation by subtracting it form both sides:

y + 3 = 2x

- 3 - 3

y = 2x - 3
