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.
