Calculating Slope from Graphs

Mr. Buffington explains the concept of slope, describing it as the steepness of a line. He categorizes slopes into steep, shallow, negative, zero, and undefined. The video emphasizes the importance of measuring slope using the rise over run method, which involves selecting any two points on a line. Through examples and practice exercises, viewers learn to calculate both positive and negative slopes. The video concludes with a recap of the key concepts and encourages further practice.

What does a steep slope look like?

• A completely vertical line

• A very steep incline

• A nearly horizontal line

• A shallow incline

What kind of slope does a horizontal line represent?

• Positive slope

• Undefined slope

• Negative slope

• Zero slope

How is slope calculated?

• Rise over run

• Height over distance

• Width over length

• Length over width

What does the slope of 2 over 1 indicate?

• A zero slope

• A steep slope

• An undefined slope

• A shallow slope

Why should slope be left as a fraction?

• To avoid decimals

• To simplify calculations

• To clearly show rise over run

• All of the above

What does a negative slope indicate?

• The line is falling

• The line is horizontal

• The line is vertical

• The line is rising

How do you calculate a negative slope?

• Subtract rise from run

• Divide rise by run

• Rise over run, considering direction

• Run over rise

What is the slope of a line that goes down 1 and over 2?

• 1/2

• -2/1

• -1/2

• 2/1

Can the slope of a line change if you pick different points on the line?

• Only on a graph without a grid

• Only if the line is curved

• Yes, always

• No, it remains constant

What is the best way to practice understanding slope?

• Ignoring negative slopes

• Memorizing formulas

• Using a calculator

• Practicing with different lines
