By looking at two linear equations, is there a way you can you tell if the corresponding lines are parallel?

Step 1. Two lines are parallel when they have the same slope, say m.

Step 2. So the two linear equations should be in slope-intercept form given as y=mx+b where m is the slope and b is the y-intercept when x=0 or at point (0,b).

Step 3. Example: y=2x+3 and y=2x-9. These two line are parallel since the slope is m=2.

I hope the above steps were helpful.
