In this chapter, we will be learning about the gradient of a straight line. The gradient tells us how steep or shallow a line is. We will start by understanding the concept of gradient and how it relates to real-life situations. We will then learn how to calculate the gradient using the ratio of vertical distance to horizontal distance. Finally, we will derive the formula for finding the gradient of a straight line on the Cartesian plane. By the end of this chapter, we will be able to determine the gradient of any straight line and understand its significance in mathematics and everyday life.
• 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
• Derive the formulae for gradient of a straight line in the Cartesian plane
• Make generalisation for the gradient of a straight line
• Determine the gradient of a straight line
• Solve problems involving the gradient of a straight line
