Answer:

Neither

Explanation:

Solve both equations for y or point Slope form.

y = 3x + 5 is already done.

Second equation

-3x - y = 9 add y - 9 to both sides

y = - 3x - 9

They have opposite slopes but not reciprocal and the slopes are not equal to each other so they are neither parallel or perpendicular.
