Answer:
Parallel to line a: y=3x-2
Perpendicular: y= -1/3x-2
Neither: y=1/3x+1
Explanation:
Parallel means that they have the same slope, which is 3x in line a. So y=3x-2 has the same slope as line a. Perpendicular means that it has the negative reciprocal, which of line a would be y= -1/3x-10. The remaining equation is for the last box, which is neither parallel or perpendicular.
