3.
Find the slope
• Rise = 5
• Run = 3
• Slope = 5/3
• Slope is positive
since both rise and
run are positive.
• Positive slope climbs
from left to right.
4.
Find the slope
• Rise
– 1
• Run
– -2
• Slope = 1/-2
• Slope is negative since
rise is positive and run is
negative.
• Negative slope climbs
from right to left.
5.
Zero Slope
• Horizontal lines
have zero slope
• 0 rise/run
6.
Undefined slope
• Vertical lines have
undefined slope
• Rise/0 run
7.
Slope formula
• Change in y (rise) over change in x (run)
