slope of a line in X-Y plane

= (change in Y coordinates)/(change in X-coordinates)

If the angle with line and X-axis is `theta` then the slope can be given as `tantheta` . This angle is also called inclination angle.

`slope = tantheta`

`slope = tantheta`

`slope = tan1.27`

`slope = 3.224`

**So the slope of the line that has inclination angle `theta = 1.27rad` is 3.224**
