Exploring Types of Slope and Graph Interpretation

What is the main goal of today's lesson?

• To memorize slope formulas

• To understand the history of slopes

• To learn about different types of graphs

• To calculate slope from a graph

Which type of slope is represented by a line that increases from left to right?

• Undefined slope

• Zero slope

• Positive slope

• Negative slope

What is the slope of a horizontal line?

• Zero

• Positive

• Negative

• Undefined

What does a vertical line represent in terms of slope?

• Zero slope

• Negative slope

• Positive slope

• Undefined slope

Which part of the face diagram represents an undefined slope?

• Nose

• Eyes

• Ears

• Mouth

What is the first step in calculating the slope from a graph?

• Count the run

• Draw a triangle

• Count the rise

• Identify two points

How do you represent the slope formula?

• Difference of x and y

• Run over rise

• Rise over run

• Sum of x and y

If a line has a rise of 2 and a run of 3, what is its slope?

• 1/2

• 2/3

• 3/2

• 3/1

Why is the slope of a vertical line considered undefined?

• Because the rise is zero

• Because the line is diagonal

• Because the line is horizontal

• Because the run is zero

What is the slope of a line that goes down from left to right?

• Positive

• Undefined

• Negative

• Zero
