The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.
Getting a perpendicular line is called the "negative inverse." With y=mx+b, m is what you are dealing with. In the equation y=3x, the perpendicular line of that is y=-1/3x M was 3/1 (same as...
They are the negative reciprocal of each other. Fo rexample, if a line has slope = +2, then the line perpendicular to it has slope -1/2
No, lines have the same slope if and only if they are parallel to each other.
if line's A and B are perpendicular to each other, the slope of A = -1/(the slope of B)
