Question 399750: Find the slope of a parallel line and the slope of perpendicular line with the equation y= -3x
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Given y=-3x, the slope of this line is m=-3.
Any line parallel to this line has the SAME SLOPE, so m= -3 for any line paralle.
Any line perpendicular to this line has a slope that is the NEGATIVE RECIPROCAL of this slope. This slope would be m=+1/3.
