Calculating the Slope of a Line

This video tutorial explains the concept of slope in mathematics, represented by the letter M. It covers how to calculate slope using the rise over run method, and discusses different types of slopes: positive, negative, zero, and undefined. The video also includes practice problems to help viewers apply the concepts learned.

What does the slope of a line represent?

• The width of the line

• The length of the line

• The steepness of the line

• The color of the line

Which letter is commonly used to represent slope in mathematics?

• S

• N

• L

• M

How is slope calculated using a graph?

• By measuring the length of the line

• By counting the number of points on the line

• By using rise over run

• By finding the midpoint of the line

If you rise 3 units and run 1 unit to the right, what is the slope?

• 1

• 3/1

• 3

• 1/3

What does a positive slope indicate when reading a graph from left to right?

• The line is going up

• The line is horizontal

• The line is vertical

• The line is going down

What is the slope of a horizontal line?

• Negative

• Positive

• Zero

• Undefined

Why is the slope of a vertical line considered undefined?

• Because the rise is zero

• Because the line is horizontal

• Because the line is diagonal

• Because the run is zero

If a line has a slope of -1/3, what does this indicate about the line?

• The line is decreasing

• The line is increasing

• The line is vertical

• The line is horizontal

What is the slope of a line that rises 6 units and runs 5 units to the right?

• 0

• 1

• 5/6

• 6/5

If a line rises 4 units and runs 2 units to the left, what is the slope?

• -2

• -1/2

• 2

• 1/2
