Question 145679: Determine whether lines are parallel, perpendicular or neither.
y=3x-4
y=3x-9
Answer by Earlsdon(6294)   (Show Source):
You can put this solution on YOUR website! y = 3x-4
y = 3x-9
Both of your equations are in the slope-intercept form, y = mx+b, so you can immediately see that the slopes, m, are equal.
If the lines have equal slopes, then they are parallel.
