A line whose slope is not constant or not defined. A curved line, a discontinuous line, a vertical line are some examples.
If the line slants up and to the right, it has a positive slope. If it is slanting up and to the left, it has a negative slope.
Th opposite reciprocal. So if one line has a slope of 2 then the other line will have a slope of -1/2
A line that is vertical, or going up and down like a pencil.
A horizontal line has a slope of zero. Also, a curve on its lowest and highest points (local maxima or local minima) normally has a slope of zero at such a point.
Any continuous line as long as it does not have a vertical section.
A line whose slope is not constant or not defined. A curved line, a discontinuous line, a vertical line are some examples.
The straight line with no slope is a point
A line that slopes to the right and up has a positive slope.
If the line slants up and to the right, it has a positive slope. If it is slanting up and to the left, it has a negative slope.
Th opposite reciprocal. So if one line has a slope of 2 then the other line will have a slope of -1/2
The line has a negative slope (or negative gradient).When the angle between the line and the positive direction of Ox is obtuse then the slope is negative. Conversely, when the angle is acute, the slope is positive.
A line extending from the upper left to the lower right has a negative slope.
A line that is vertical, or going up and down like a pencil.
Positive
A line extending from the lower left to the upper right has a positive slope.
