Proportional Relationships & Slope

Slope

• is an ordered pair on the line

• shows the steepness of a line

• is a line on a graph

• is the distance a line travels

Which of the following are ways to find the slope?

• change in y over change in x
• rise over run
• vertical change over horizontal change

• all of the above

What is the easiest/quickest way to find slope from a graphed line?

• Rise over Run
• Run over Rise
• Slope Formula

• ordered pairs

If the rise is 4 and the run is 2, what is the slope?

• 1

• 0

• 3

• 2

If the rise is -3 and the run is 5, what is the slope?

• 3/5

• 5/3

• -3/5

• 3

What is the slope of the graphed line?

Find the slope:

• 3/4
• 4/3
• -3/4
• -4/3

What is the rise on the following line?

• 1

• 4

• -4

• Undefined

What is the slope formula?

•  $m\ =\ \frac{y_2-\ y_1}{x_{2\ }-\ x_1}$  

•  $\left(x_1,\ y_1\right)\ \left(x_2,\ y_2\right)$  

•  $m\ =\ \frac{x_2-\ x_1}{y_{2\ }-\ y_1}$  

Using the slope formula, what is the slope of the line that passes through these two points?

• 3/2

• 2/3

• 4/6

• 1/2
