2
Finding The Slope of a Line
3
Slopes are commonly associated with mountains.
4
The slope we are studying is associated with the graph of a line.
5
Definitions of Slope Measures steepness Ratio of rise over run The change in y over the change in x
6
Steepness
7
Vertical Change Horizontal Change This ratio is also known as Rise Run
8
Given a graph 1.Find 2 points 2.Count Rise (y) and Run (x) 3.Rise and reduce (check direction + -) Run
9
Find Slope
10
Find the slope of the following line.
11
The slope is… 1 2
12
Find the slope of the line.
13
The slope is…. -3
14
Given an equation 1.Solve for y 2.Coefficient of x = m
15
y = 2x + 8
16
Given 2 points 1.Stack points 2.Change in y (rise) 3. Change in x (run) 4. Rise/run and reduce
17
(3, 8) and (2, 6)
18
Given a table 1.Find change in y (rise) 2.Find change in x (run) 3. Rise/ Run and reduce
