- The slope of a line is a number that describes both the direction and the steepness of the line. Usually, the slope of the line is denoted by m. <br/>
- A zero value of a slope(m = 0) in a line indiciates that the given line is horizontal. <br/>
- A line with undefined value of slope indicates that the given line is vertical. <br/>
- A line with positive value of slope(m > 0) indicates that the given line is going up from left to right.<br/>
- A line with negative value of slope(m <0)indicatesthatthegivenlineisgoingdownfromrighttoleft.<br/>
### Calculating the slope of a line when two co-ordinates of the points on the line are given
In this case, suppose a line l has two points with co-ordinates (x<sub>1</sub>,y<sub>1</sub>) and (x<sub>2</sub>,y<sub>2</sub>) then the slope of a line is calculated as:
