Exploring the Slope Formula

This video tutorial explains how to calculate the slope of a line using two points and the slope formula. It covers different types of slopes, including positive, negative, zero, and undefined slopes. The tutorial demonstrates how to use coordinates to find the rise and run, and how to apply the slope formula with examples. It emphasizes the importance of consistency when choosing points for the formula.

What is the primary method introduced in the video for calculating slope?

• Using a ruler

• Using a calculator

• Using two points and the slope formula

• Using a graph

What type of slope is indicated by a line that increases from left to right?

• Undefined slope

• Positive slope

• Zero slope

• Negative slope

If a line has zero rise between two points, what is the slope?

• Positive

• Negative

• Zero

• Undefined

What is the slope of a line if the rise is 3 and the run is 0?

• Positive

• Negative

• Undefined

• Zero

Which values are used to calculate the rise in the slope formula?

• Neither X nor Y values

• Both X and Y values

• Y values

• X values

How do you find the run using coordinates?

• Subtract the X values

• Add the X values

• Subtract the Y values

• Add the Y values

What is the slope formula derived in the video?

• y1 - y2 / x1 - x2

• x2 - x1 / y2 - y1

• y2 - y1 / x2 - x1

• x1 - x2 / y1 - y2

If the points (2, 3) and (8, 6) are used, what is the slope of the line?

• 2/3

• 1/2

• 3/2

• 1/3

What happens to the slope if you switch the points in the formula?

• It doubles

• It halves

• It remains the same

• It becomes negative

What should you do to ensure accuracy when using the slope formula?

• Ignore the order of points

• Use only positive coordinates

• Switch points randomly

• Always start with the same point for both rise and run
