Answer:
The answer is option A
Step-by-step explanation:
Since the lines are perpendicular the slope perpendicular line is the negative inverse of the original line and when they are multiplied should give - 1
Let m be the slope of the perpendicular line
That's
1/3 × m = - 1
multiply through by 3
m = - 3
The slope of the perpendicular line is - 3
