All things considered, you know that for a line to be parallel it needs to have a similar slant. In the event that you unravel the condition for y you see that:
y=-2x-5
So the incline is - 2.
Utilizing incline capture shape (y=mx+b)
you can compose your new line as:
y=-2x+2 (the - 2 we got from the reality its parallel, and the 2 is the y-block)
At that point simply rework it to standard shape.
y+2x=2
