Question 314285: y=x+ 7
y=x+2
are these lines parallel, perpendicular, or neither?

The lines are parallel because they have the same slope.
How do I know this?
Look at the number next to x.
Any letter by itself means there is an "invisible" 1 there.
The slope of both equations is 1.
Since they have the same slope, the lines are parallel.
Understand?
