Chapter 8 – Functions and Graphing
8.4 - Slope
The Tile Problem
Create a table to show the pattern.
Dark White
1
2
3
4
5
What expression can we use to show the relationship between the dark and white tiles?
w = 2d + 6Where else can we find a “2” in a pattern?
Slope
• The slope m of a line describes its steepness.
• The vertical change is called the change in y.
• The horizontal change is called the change in x.
Formulas for Slope
Slope or m = change in y
change in x
m = . y2 – y1
x2 – x1
m =rise

The House That Slope Built
Zero Slope…Zero Fun!
Positive Slope Negative Slope
No Slope!!!
NOT SAFE!!!
Graph a line that passes through (-2, 3) and (3, -3). Find the slope of the line.
Find the slope of the line that contains A(2,6) and B(-3, -8). Then graph the line.
Find the slope of each line.
