The table below represents the total number of laps Jessica swam in the pool this summer:

Week Laps

1 18

2 28

3 38

4 48


If the linear function representing the number of laps Jessica swam each week is f(w) = 10w + 8, what does the 10 represent in this function?


The number of laps Jessica swam in week 0

The week of the summer that Jessica swam

The number of laps Jessica swam in total

The number of laps Jessica increased her swim by each week

Verified Answer :

It would be the last one for the answer

Compare the linear function given with the slope-intercept form of a line, given by,

\(y=mx+b\)

Where m is the slope and b is the y-intercept.


Comparing tells us that 10 is the slope. What does it mean?

It means for every unit increase in w (weeks), there is a 10 unit increase in number of laps.

This is choice 4.


ANSWER: "The number of laps Jessica increased her swim by each week"
