Are the lines 3x - y = -2 and x - 3y = -9 parallel, perpendicular or neither
**
3x - y = -2
y=3x+2
slope=3
..
x - 3y = -9
3y=x+9
y=x/3+3
slope=1/3
..
If lines were parallel, slopes would be the same.
If lines were perpendicular, slopes would be negative reciprocals of each other.
lines are neither parallel or perpendicular
