Perpendicular
This is because lines that are perpendicular have slopes that are the negative reciprocals of each other (for example: 5 and -1/5)
When you simplify each of the equations given, the equations are:
Y=3x + 5/2
Y=-1/3x + 1/6
Since the lines are are the form y=mx + b, and ‘m’ represents the slopes, the two slopes are 3 and -1/3 which are negative reciprocals of each other, therefore the lines are perpendicular
