Grover Elementary School is getting ready for the annual Penny Drive. The table below shows the target goals for the drive at th
e end of different weeks. Time
Week 1
Week 3
Week 5
Week 7
Total money $ 3,000
$ 3,400
$ 3,800
$ 4,200
If the students express the total as a function of the number of weeks that the Penny Drive has been open, what is the slope of that function?
The slope of a function is the rate of change of the dependent variable with respect to the independent variable. The equation that represents a function is: y = mx + b
Where:
y = dependent variable
m = independent variable
x = slope
b = constant
Looking at the total money raised, the amount of money increases by 400. This is the slope.
