RATE OF CHANGE IN THE REAL-WORLD
When we calculate a rate of change, we say our answer as…
per
EXAMPLE: The graph below shows the number of miles that Darius has driven
based on the number of hours.
Calculate the rate of change for each segment of his trip.
(HINT: Count the rise by 10’s and
Count the run by ½’s)
A to B
Rate of Change = rise =
run
B to C
Rate of Change = rise =
run
C to D
Rate of Change = rise =
run
D to E
Rate of Change = rise =
run
What is Darius’ driving rate between C and D?
When is Darius driving the fastest?
When is Darius driving the slowest?
NOTES 6.7 NAME:
YOUR TURN: The graph below shows the amount of money that Latoya has
based on the number of days.
Calculate the rate of change for each segment of the graph.
(HINT: Count the rise by 5’s and Count
the run by 1’s)
A to B
Rate of Change = rise =
run
B to C
Rate of Change = rise =
run
C to D
Rate of Change = rise =
run
D to E
Rate of Change = rise =
run
What is Latoya’s rate of change between B and C?
Between what points is Latoya earning money?
Between what points is Latoya spending money?
Between what points is Latoya earning the money at the fastest rate?
Between what points is Latoya spending money at the fastest rate?
