The coefficient of x is the slope

Parallel lines slope the same way.
That is, they have the same slope

The coefficient of x in  is .

Therefore the slope of  is . 

The coefficient of x in  is . 

Therefore the slope of  is .

 is the equation of a line parallel to the line .

Therefore  must be the same as 

Answer 

Result:

 is the equation of a line parallel to the line .
