Understanding Slope

The video tutorial introduces the concept of slope, explaining it through two lines, M and N. Line M has a positive slope, moving upward from left to right, while line N has a negative slope, moving downward. The slope is defined as the rise over run, representing the change in the Y direction over the change in the X direction. The tutorial provides step-by-step calculations for determining the slopes of both lines, emphasizing the importance of counting the rise and run accurately. The video concludes with a summary of the key points discussed.

What is the direction of a line with a positive slope?

• It forms a vertical line.

• It goes upward from left to right.

• It remains horizontal.

• It goes downward from left to right.

How do you determine the slope of a line?

• By multiplying the rise by the run.

• By dividing the change in X by the change in Y.

• By dividing the change in Y by the change in X.

• By adding the rise and the run.

What is the slope of line M if the rise is 3 units and the run is 1 unit?

• 1/3

• 3

• 1

• 3/1

For line N, if the rise is -1 and the run is 4, what is the slope?

• 4

• -4

• 1/4

• -1/4

Why is the slope of line N negative?

• Because the line slopes downward from left to right.

• Because the line slopes upward from left to right.

• Because the line is horizontal.

• Because the line is vertical.

What is the general rule for counting the run in slope calculation?

• Always count the run as negative.

• Count the run based on the direction of the rise.

• Always count the run as positive.

• Ignore the run in slope calculation.

What should you do first when determining the slope direction?

• Count the run first.

• Count the rise first.

• Ignore the rise and run.

• Count both simultaneously.
