Understanding Slope and Graphs

The video tutorial covers the concept of slopes in graphs, explaining that slopes can be positive, negative, or zero. It demonstrates how to calculate the slope of graph D, which is negative, and graph E, which is zero. The tutorial also provides real-life examples of situations with zero slope, such as constant rainfall or ticket fare. Finally, it guides viewers on drawing a line with a slope of -2.

What are the possible types of slopes a graph can have?

• Only zero

• Positive, negative, or zero

• Only positive

• Only negative

How do you calculate the slope of a graph?

• By adding the horizontal and vertical changes

• By dividing the vertical change by the horizontal change

• By subtracting the horizontal change from the vertical change

• By multiplying the horizontal and vertical changes

What is the slope of Graph D if the vertical change is -8 and the horizontal change is 2?

• 2

• -2

• 4

• -4

What does a slope of zero indicate about a graph?

• The graph is increasing

• The graph is decreasing

• The graph is constant

• The graph is vertical

Which of the following is an example of a situation with a slope of zero?

• A car accelerating

• A plane taking off

• A ball rolling down a hill

• A constant number of customers in a store

What is the horizontal change if a line has a slope of negative two and a vertical change of -4?

• 1

• 3

• 4

• 2

How does a line with a negative slope appear on a graph?

• Vertical

• Horizontal

• From upper left to lower right

• From lower left to upper right

If a line goes down two units for every one unit it goes to the right, what is its slope?

• -2

• -1

• 2

• 1

What is the vertical change if a line has a slope of -2 and a horizontal change of 2?

• 4

• 2

• -2

• -4

Which direction does a line with a slope of negative two move?

• Horizontally

• Upwards

• Downwards

• Vertically
