Can someone please help. When graphing the equations y = 2x – 2, y = 2x, and y = 2x + 3, what observation can you make about the graphs. Can you make the same observation before graphing the lines? How? Thanks

Steve,
The lines are parallel.
the slopeintercept form of the equation y=mx+b gives the slope.
All of these lines are y=2x+b for b=2,0,3. They all have the same slope, so they are parallel.
