Understanding Slopes

The video tutorial introduces the concept of slopes, focusing on positive, negative, horizontal, and vertical slopes. It explains how to calculate slopes using the rise over run method and discusses special cases like horizontal lines with zero slope and vertical lines with undefined slope. The tutorial concludes with a summary of the slopes and their corresponding equations on the Cartesian coordinate plane.

What is the slope of a line that rises 4 units and runs 3 units?

• 4/3

• 3/4

• 1/2

• 2/1

If a line goes down 2 units and over 2 units, what is its slope?

• -1

• 1

• 0

• 2

What is the slope of a horizontal line?

• Undefined

• Negative

• Zero

• Positive

What is the equation of a horizontal line that crosses the y-axis at 2?

• x = 0

• x = 2

• y = 0

• y = 2

Why is the slope of a vertical line considered undefined?

• Because the run is zero

• Because it has a positive slope

• Because the rise is zero

• Because it has a negative slope

What is the equation of a vertical line that crosses the x-axis at 2?

• x = 2

• y = 2

• x = 0

• y = 0

Which type of slope does a line have if it goes up from left to right?

• Positive

• Negative

• Zero

• Undefined

Which type of slope does a line have if it goes down from left to right?

• Zero

• Positive

• Undefined

• Negative

What is the slope of a line that has no rise?

• Undefined

• Negative

• Zero

• Positive

What is the equation of a line that crosses the y-axis at -2?

• x = -2

• y = -2

• y = 0

• x = 0
