Chapter 10- Gradient of a Straight Line

Chapter 10- Gradient of a Straight Line

10.1 Gradient

10.1.1 Steepness and inclination area

Describe gradient and direction of inclination based on real life situations, and then explain the meaning of gradient as a ratio of vertical distance to horizontal distance

Gradient

• Gradient is the degree of steepness

• Gradient is normally connected with the height of a mountain

• But did you know every object that has a slope(inclination) has a gradient
