Question

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

Answer 1

It would be the last one for the answer

Answer 2

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"
