Calculating Gradients and Methods

The video tutorial explains two methods for finding the gradient of a line: an easy method suitable for simple diagrams and a trickier method for more complex cases. The teacher demonstrates how to select two points on a line, calculate the rise and run, and apply the gradient formula. The tutorial emphasizes the importance of understanding both methods to handle different types of diagrams effectively.

What is a limitation of the easy method for calculating gradients?

• It is applicable to all types of diagrams.

• It only works with complex diagrams.

• It requires whole numbers and simple diagrams.

• It can only be used with vertical lines.

In the trickier method, what is the first step to find the gradient?

• Pick any two points on the line.

• Draw a triangle on the diagram.

• Calculate the area under the line.

• Use a calculator to find the slope.

What does the 'rise' in the rise over run formula represent?

• The angle of the line with the x-axis.

• The total length of the line.

• The vertical distance between two points.

• The horizontal distance between two points.

How do you calculate the 'run' in the rise over run formula?

• Subtract the x-values of the two points.

• Add the x-values of the two points.

• Multiply the x-values of the two points.

• Subtract the y-values of the two points.

What are the coordinates of the first point used in the example?

• (3, 4)

• (5, 6)

• (4, 3)

• (1, 5)

What is the gradient calculated in the example provided?

• 4

• 3

• 2

• 1

What is the formula used to calculate the rise?

• x2 - x1

• y2 - y1

• x1 + x2

• y1 + y2

Why might you choose the trickier method over the easy method?

• When the points do not align with whole numbers.

• When the diagram is simple and clear.

• When you want to avoid using algebra.

• When the line is horizontal.

What is the main advantage of using the easy method?

• It requires no calculations.

• It works for all types of lines.

• It is faster and simpler for whole numbers.

• It is more accurate.

What should you do if the diagram does not match up to a nice easy point?

• Use the easy method anyway.

• Use the trickier method with two points.

• Ignore the diagram.

• Draw a new diagram.
