A line with a negative slope will slant down from left to right.
A line with a positive slope will slant up from left to right.
When calculating slope, the rise is the vertical distance between two specified points.
When calculating slope, the run is the horizontal distance traveled.
Slope is a measure of the steepness of a line. A line can have positive, negative, zero (horizontal), or undefined (vertical) slope. The slope of a line can be found by calculating “rise over run” or “the change in the over the change in the .” The symbol for slope is
