# Slope of a line :

**The Slope of a straight line is defined as that it is described direction and as well as steepness of a line.**

**Or **

**The Slope of a line can be defined as that it is changing rate of y with respect to x in x-y plane.**

**Notation : Generally slope is denoted by m or tanθ .**

**Slope = m = tanθ .**

**here θ is an angle between the line and positive direction of x-axis.**
