Calculating Line Gradients

The video tutorial explains the concept of gradient, a measure of line steepness, and demonstrates how to calculate it using three methods: rise over run, change in y over change in x, and a simple rise per unit run. It uses examples of hills and graphs to illustrate positive, zero, and negative gradients. The tutorial emphasizes understanding gradient calculation through equations and practical examples.

What is the primary purpose of calculating the gradient of a line?

• To determine the color of the line

• To find out how steep the line is

• To calculate the area under the line

• To measure the length of the line

Which hill has the highest gradient?

• The one that is completely flat

• The one that increases in height most quickly

• The one that is less steep

• The one that is sloping downwards

How do you calculate the gradient using the rise over run method?

• By adding the rise and the run

• By dividing the rise by the run

• By measuring the distance between two points

• By subtracting the run from the rise

What is the gradient of a line that rises by 0.5 for every unit it goes across?

• 2.0

• 1.0

• 0.5

• 0.0

What does the equation 'change in y divided by change in x' represent?

• The length of the line

• The gradient of the line

• The area under the line

• The midpoint of the line

If a line goes from x = -4 to x = 2, what is the change in x?

• 8

• 4

• 6

• 2

What is the gradient of a line that does not rise at all?

• 1

• 0

• 2

• -1

How do you determine the gradient of a downward sloping line?

• By measuring the length of the line

• By determining the color of the line

• By calculating the positive rise over run

• By finding the negative rise over run

What is the gradient of a line that goes down from 3 to -3 on the y-axis?

• -6

• -1

• -2

• -3

Which method can be used to calculate the gradient of a line?

• Rise over run

• Area calculation

• Length measurement

• Color analysis
