Understanding Slope and Its Types

The video tutorial explains the concept of slope, defined as rise over run. It covers four types of slopes: undefined, positive, negative, and zero. Undefined slope occurs when a line is vertical, positive slope when the line rises, negative slope when it falls, and zero slope when the line is horizontal. Each type is illustrated with examples to aid understanding.

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

• Distance over time

• Rise over run

• Run over rise

• Time over distance

What type of slope is present when a line goes straight up and down?

• Undefined slope

• Negative slope

• Zero slope

• Positive slope

If a line has a rise of 6 and a run of 6, what type of slope does it have?

• Zero slope

• Positive slope

• Undefined slope

• Negative slope

Which of the following describes a positive slope?

• The line goes upward

• The line goes downward

• The line is horizontal

• The line is vertical

What is the rise of a line if it starts at -9 and goes downward?

• 8

• 9

• 0

• -9

If a line has a rise of -9 and a run of 8, what type of slope does it have?

• Zero slope

• Negative slope

• Positive slope

• Undefined slope

What type of slope is present when a line is perfectly horizontal?

• Zero slope

• Positive slope

• Negative slope

• Undefined slope

If a line has no rise and a run of 4, what is the slope?

• Zero

• Negative

• Undefined

• Positive

Which of the following is NOT a type of slope?

• Circular slope

• Positive slope

• Negative slope

• Zero slope

How do you determine the type of slope a line has?

• By checking the color of the line

• By measuring the angle of the line

• By determining the rise over the run

• By counting the number of points on the line
