Finding Slope from Line Graphs

What is the main goal of this tutorial?

• To calculate the slope of any line on a graph

• To explore the history of slope calculation

• To understand the concept of slope

• To learn about different types of graphs

Which of the following is NOT a way to express the slope formula?

• Rise over run

• Sum of Y and X

• Change in Y over change in X

• Y2 minus Y1 over X2 minus X1

If the rise is 1 and the run is 3, what is the slope?

• 3/1

• 1/3

• 1

• 3

Does the order of points affect the slope calculation?

• No, but only for negative slopes

• Yes, but only for positive slopes

• No, the slope remains the same

• Yes, it changes the slope

What happens if you switch the coordinates in the slope formula?

• The slope becomes negative

• The slope remains the same

• The slope becomes undefined

• The slope doubles

What is the slope of a line if you choose points (0,1) and (3,-1)?

• -1/3

• 2/3

• -2/3

• 1/3

What is the slope of a horizontal line?

• Undefined

• 0

• 1

• Infinity

What is the slope of a vertical line?

• Undefined

• 1

• Infinity

• 0
