Finding Slope from a Graph

This video tutorial teaches how to find the slope from a graph using the concept of rise over run. It covers different types of slopes: positive, negative, zero, and undefined, with examples for each. The tutorial emphasizes using a right triangle to determine the rise and run, and how to use a calculator to convert results into fractions or decimals. It also highlights the importance of identifying 'pretty points' on a graph for accurate calculations.

What is the term used to describe the vertical change in a graph?

• Gradient

• Rise

• Slope

• Run

If a graph is going upwards from left to right, what type of slope does it have?

• Zero

• Undefined

• Positive

• Negative

How do you calculate the slope of a line?

• Run over rise

• Sum of x and y

• Change in y over change in x

• Product of x and y

What is the slope of a line that goes down 2 units and right 2 units?

• -2

• 1

• -1

• 2

What is the slope of a line that does not rise at all?

• Negative

• Positive

• Undefined

• Zero

If a line has a rise of 0 and a run of 1, what is its slope?

• Undefined

• -1

• 0

• 1

What type of slope does a vertical line have?

• Negative

• Positive

• Undefined

• Zero

What happens when you divide a number by zero in the context of slope?

• It is undefined

• You get a negative number

• You get a positive number

• You get zero

What should you look for on a graph to find points for calculating slope?

• Any random points

• Points on the x-axis

• Points on the y-axis

• Points at perfect corners

If you find two points on a graph at (-3, 2) and (1, 2), what is the slope?

• -1

• Undefined

• 1

• 0
