Parallel lines have the same slope.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.

The slope of a line that has the points 3, (-4), and has a slope of 2 is 2.

Perpendicular line = - 1/gradient= - 1/2/3= - 3/2

Parallel lines have the same slope.

if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.

The slope of two lines are perpendicular only if their slopes multiplied together equal -1 (m1*m2 = -1). So if a line has a slope of -3 then a line perpendicular to this one has a slope of -1/-3 or 1/3.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.

Slope of a line = m slope of perpendicular line = -1/m

The slope of a line that has the points 3, (-4), and has a slope of 2 is 2.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of a line that is perpendicular to a line with a slope of -2/3 is 3/2, (or 11/2 or 1.5).

Two points don't have a slope. But the line between them does. The line between the points (-5, 3) and (3, 3) has a slope of zero.

-5/3 it is always the opposite reciprocal for a perpendicular slope

Slope of the given line is 3/7 So slope of perpendicular line is -7/3
