Understanding Slopes

The video tutorial explains how to find the slope of a line by using the ratio of the vertical rise to the horizontal run. It emphasizes the importance of identifying two points on the line that intersect the grid corners and considering the scale factor when calculating the slope. The tutorial also covers different types of slopes, including positive, negative, undefined, and zero slopes, and explains special cases such as vertical and horizontal lines.

What is the first step in finding the slope of a line?

• Identify two points on the line

• Calculate the area under the line

• Find the midpoint of the line

• Determine the length of the line

How do you determine the rise in a slope calculation?

• By measuring the horizontal distance

• By counting the vertical change between two points

• By finding the midpoint of the line

• By calculating the area under the line

Why is it important to consider scale factors when calculating slope?

• They are used to calculate the area under the line

• They help in finding the midpoint of the line

• They determine the color of the graph

• They affect the actual numerical values of rise and run

If a line has a rise of 6 and a run of 2, what is the slope?

• 4

• 1

• 2

• 3

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

• The line is vertical

• The line is horizontal

• The line is moving upward

• The line is moving downward

How is a negative slope identified on a graph?

• The line is horizontal

• The line is vertical

• The line moves downward from left to right

• The line moves upward from left to right

What is the slope of a vertical line?

• Undefined

• Negative

• Positive

• Zero

What is the slope of a horizontal line?

• Undefined

• Zero

• Positive

• Negative

What happens if you try to calculate the slope of a vertical line using a calculator?

• It returns an error

• It returns a positive number

• It returns zero

• It returns a negative number

Which of the following is true about a line with a slope of zero?

• It is vertical

• It moves downward from left to right

• It moves upward from left to right

• It is horizontal
