Comparing Slope Formula and Rise Over Run

Mr. Dallas explains the concept of slope, comparing the slope formula and rise over run method. He demonstrates how to calculate slope using both methods with examples, highlighting when each method is preferable. The video emphasizes the efficiency of rise over run when a graph is available and the necessity of the slope formula when a graph is not present.

What is the main topic discussed in the video?

• The Pythagorean theorem

• Slope and its calculation methods

• Quadratic equations

• Trigonometric functions

Which formula is used to calculate slope when a graph is not available?

• Pythagorean theorem

• Slope formula

• Quadratic formula

• Rise over run

What is the first step in using the slope formula?

• Substitute the values

• Simplify the equation

• Write down the equation

• Label the coordinates

In the example problem, what are the coordinates of point E?

• (6, 5)

• (8, -2)

• (8, 2)

• (6, -5)

What is the slope between points E (6, -5) and F (8, 2) using the slope formula?

• 2/5

• 5/2

• 7/2

• 2/7

When is it best to use the rise over run method?

• When you have a graph

• When you don't have a graph

• When solving for the hypotenuse

• When dealing with quadratic equations

How do you determine the rise in the rise over run method?

• By counting the horizontal distance

• By using the quadratic formula

• By counting the vertical distance

• By using the Pythagorean theorem

What is the slope of the line segment RS using rise over run?

• 5/13

• 13/5

• 3/7

• 7/3

Which method is generally quicker for finding the slope when a graph is available?

• Slope formula

• Quadratic formula

• Rise over run

• Pythagorean theorem

What is a potential disadvantage of using the slope formula?

• It requires a graph

• It can only be used for vertical lines

• It involves more complex calculations

• It is less accurate
