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.
Parallel lines have the same slope. This means that if two lines are parallel, the ratio of the change in y to the change in x (rise over run) is identical for both lines. Consequently, they will never intersect, maintaining a constant distance apart. In mathematical terms, if one line has a slope of m, the other line will also have a slope of m.
Parellel lines
It can be parellel like this ---------------------------------------------- ----------------------------------------------
parellel lines
They are lines of latitude.
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.
