Slope in Terms of Inclination

Slope in Terms of Inclination

## Formula

If a line makes an angle $$\theta$$ with the positive direction of the $$x$$-axis:

$$m=\tan\theta$$

## Terminologies

- $$\theta$$ → Inclination of the line with the positive $$x$$-axis.

## Usage

- Used to determine the slope when the inclination angle is known.
