divide 9 from both sides to isolate the y

What is the slope of a line that is parallel to the line y = x + 2?
BigorU [14]
A slope of any line parallel to y = x + 2 will be 1. 

The slope of parallel lines are always equal. Since we do not see a number next to the x in the original equation, there is an assumed 1 there. Therefore any line that is parallel with it would also have to be 1.
