Slope

Lesson 5.5

Slope

• Slope is the rate of change between any two points on a line.

• To find the slope of a line, find the ratio in the change in y to the change in x.

•  $slope=\frac{rise}{run}$  

Finding Slope

• Use the points (3,4) and (0,0) to find the slope.

Finding Slope

• Use the points (4,1) and (-2,-2) to find the slope of the line.

Multiple Choice

Find the slope of the line.

(5,2) (0,0)

• $-\frac{2}{5}$

• $\frac{2}{5}$

• $-\frac{5}{2}$

• $\frac{5}{2}$

Multiple Choice

Find the slope of the line.

(1,5) (2,8)

• $\frac{1}{3}$

• $-\frac{1}{3}$

• $\frac{3}{1}$

• $-\frac{3}{1}$

Interpreting Slope

• Graph the data.

• Find and interpret the slope of the line through the points.

Interpreting Slope

• The graph shows the amounts you and your friend earn babysitting.

• Compare the steepness of the lines. What does this mean in the context of the problem?

• Find and interpret the slope of each line.
