Finding The Gradient Of A Straight Line

In this video, Lucy explains how to find the gradient of a straight line from a graph. The gradient indicates the steepness of a line, with positive gradients for lines going upwards and negative for downwards. Lucy demonstrates how to calculate the gradient using two exact points on the line, forming a triangle to determine the rise and run. She provides examples of both positive and negative gradients, explaining their significance in real-world contexts like speed on a distance-time graph. The video concludes with a preview of finding the equation of a line in the next video.

What does the gradient of a line indicate?

• The color of the line

• The steepness of the line

• The width of the line

• The length of the line

Which of the following is true about a positive gradient?

• The line moves downward as it goes from left to right

• The line is horizontal

• The line moves upward as it goes from left to right

• The line is vertical

How do you calculate the gradient of a line?

• Divide the run by the rise

• Multiply the rise by the run

• Add the rise and the run

• Divide the rise by the run

What is the gradient if the rise is 6 and the run is 3?

• 2

• 3

• 0.5

• 1

What does a negative gradient signify in terms of graph movement?

• The line is vertical

• The line moves downward as it goes from left to right

• The line is horizontal

• The line moves upward as it goes from left to right
