 Question 468316: Indicate which of the following sets of lines are parallel, perpendicular, or neither. 3x + y = 5. X + y = 3. Answer by algebrahouse.com(1079)   (Show Source): You can put this solution on YOUR website!Parallel lines have the same slope. Perpendicular lines have slopes which are negative reciprocals. Slope-intercept form is y = mx + b m is the slope of the line b is the y-intercept of the line 3x + y = 5 y = -3x + 5 {subtracted 3x from both sides} slope = -3 x + y = 3 y = -x + 3 {subtracted x from both sides} slope = -1 = neither These two lines are neither, parallel nor perpendicular, because the slopes are not equal, nor are they negative reciprocals.
