Exploring the Slope of a Line

This video tutorial by Mr. Becker explains the concept of slope, which measures the steepness of a line. It introduces the slope formula, which compares the vertical change (rise) to the horizontal change (run) using Delta Y and Delta X. The video provides examples of calculating slope with different point pairs, demonstrating positive, negative, zero, and undefined slopes. Each example is explained step-by-step, highlighting the importance of consistent subtraction order and the characteristics of lines with different slopes.

What does the slope of a line represent?

• The steepness of the line

• The length of the line

• The width of the line

• The color of the line

Which letter is used to represent slope?

• S

• L

• N

• M

What is the formula for calculating the slope of a line?

• (y1 - y2) / (x1 - x2)

• (x1 - x2) / (y1 - y2)

• (x2 - x1) / (y2 - y1)

• (y2 - y1) / (x2 - x1)

Why is it important to be consistent with the order of subtraction when calculating slope?

• To make the calculation easier

• To get the correct value of the slope

• To ensure the slope is always positive

• To avoid getting a negative slope

What is the slope of the line passing through the points (1,1) and (3,4)?

• 3/2

• 2

• 1/2

• 2/3

What does a positive slope indicate about the direction of the line?

• The line goes up from left to right

• The line is vertical

• The line is horizontal

• The line goes down from left to right

What is the slope of the line passing through the points (-1,2) and (4,-2)?

• -4/5

• 4/5

• -5/4

• 5/4

What does a zero slope indicate about the line?

• The line is vertical

• The line is horizontal

• The line is undefined

• The line is diagonal

What is the slope of the line passing through the points (2,1) and (6,1)?

• 0

• 2

• Undefined

• 1

What is the slope of a vertical line?
