Slope of a line = m slope of perpendicular line = -1/m
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
It was the French mathematician Rene Descartes who introduced coordinate geometry that includes the slope of a straight line on the Cartesian plane.
The line perpendicular to a line with a slope of 1/5 has a slope of -5.
The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
The lines below are perpendicular. If the slope of the green line is -1, what is the slope of the red line?
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.
Parallel lines have the same slope. The slope of the second line is also 13.
The slope of a line is undefined if the line is vertical.
The slope of a line measures the steepness of the line.
