The graph of [ y = 4x + 2 ] is a straight line with a slope of 4.Any line with a slope of 4 is parallel to that one, and any line parallel to that one has a slope of 4.
They don't, they are parallel to each other.
Parellel lines
It can be parellel like this ---------------------------------------------- ----------------------------------------------
They are lines of latitude.
parellel lines
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
Slope of a line = m slope of perpendicular line = -1/m
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.
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.
The lines below are perpendicular. If the slope of the green line is -1, what is the slope of the red line?
