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

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.
