 Question 447710: Determine whether each pair of equations represents parallel lines. y=1/3x-2 y=-1/3x+1Answer by Leaf W.(97)   (Show Source): You can put this solution on YOUR website!When in the format y = mx + b, as these equations are, one can look at the 'm' to know the slope. For these, the slopes are and . Slopes that are the SAME (identical) between equations name PARALLEL lines. However, since one of your slopes is positive and the other is negative, the slopes are NOT parallel. ***THEREFORE, THIS PAIR OF EQUATIONS DOES NOT REPRESENT PARALLEL LINES.
