1. Introduction
To Slope

2. Slope (Middle box) Measures steepness of a line Rate of change
“m” = symbol for slope

slope

3. Slope #1 - Positive Slope
Always look at the slope from left to right
“Uphill”
Ex: m = 3, 2 3 , , 9, 2 1

4. Slope #2 - Negative Slope
Always look at the slope from left to right
“Downhill”
Ex: m = -1, − 4 7 , − 5 2 , -6, − 3 1

5. Slope #3 - Zero Slope Horizontal Line Numerator is 0
Ex of slope: m = 0, 0 8

6. Slope #4 - Undefined Slope
No slope to the line
Vertical Line
Denominator is 0
Ex of slope: m = − 7 0 , 5 0
