Understanding Slope and Line Characteristics

This video tutorial teaches how to find the slope of a line from a graph, covering positive, negative, zero, and undefined slopes. It explains the concept of rise over run and demonstrates how to calculate the slope using examples. The video also discusses the consistency of slope regardless of the points chosen and explores the slopes of horizontal and vertical lines. The tutorial concludes with a summary of the different types of slopes.

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

• Difference between rise and run

• Rise over run

• Run over rise

• Sum of rise and run

If a line moves 3 units up and 4 units to the right, what is the slope?

• 3/4

• 4/3

• 7

• 1

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

• The line goes down as you move from left to right.

• The line is horizontal.

• The line goes up as you move from left to right.

• The line is vertical.

How do you determine the slope of a line with a negative rise of 1 and a run of 2?

• 1/2

• -1/2

• 2

• -2

What remains constant regardless of which points you choose on a line?

• The coordinates

• The slope

• The rise

• The run

What is the slope of a line that moves 2 units up and 2 units to the right?

• 0

• 1

• Undefined

• 2

What is the slope of a horizontal line?

• Undefined

• 1

• Positive

• 0

Why is the slope of a vertical line considered undefined?

• Because the line is horizontal

• Because both rise and run are zero

• Because the run is zero

• Because the rise is zero

Which type of line has a slope of zero?

• Diagonal line

• Horizontal line

• Vertical line

• Curved line

What type of slope does a line have if it falls from left to right?

• Undefined

• Negative

• Zero

• Positive
