Question 721495: Which of the following could be the equation of a line perpendicular to the line "y=3x-6"?
A y= 1/3x - 6
B y= 3x + 2
C y= -3x + 2
D y= -1/3x - 6
Answer by ajones305(5)   (Show Source):
You can put this solution on YOUR website! Because a perpendicular line is the OPPOSITE RECIPROCAL of the original line's slope (m, the value that comes before the x),your answer is D, y=-1/3x-6.
EXPLANATION:
Y=3x-6
First, find the reciprocal of 3. (1/3)
Now, Find the opposite of 1/3 (-1/3)
