To determine this you will need to compare the slopes of the two lines.
Parallel lines have identical slopes.
Perpendicular lines have slopes that are the negative reciprocal of each other.
If the slopes are none of the above, then the lines are neither parallel nor perpendicular.
The given equations are, conveniently, already in slope-intercept form: y = mx+b, so you can read the slopes, m, of the two lines.
Slope 1:
Slope 2:
As you can see, the slope are neither equal nor negative reciprocals, so the lines are neither parallel nor perpendicular.
