Q. Christine uses a GPS fitness device to track her steps while she walks to school and then around the track. The graph shows the relationship between the number of laps around the track she completes and the total number of steps she takes.

\newline

\newline

How many steps does Christine take to get from her home to the track?

\newline

\_\_\_

steps

\newline

Complete the equation to represent the relationship between the total number of steps Christine takes,

S

, and the number of laps she completes,

n

.

\newline

S = \_\_\_ n + \_\_\_

Start Point Identification: Look at the graph where it crosses the y-axis; this is the starting point before any laps are completed, which represents the steps from home to the track.
Y-Axis Value Reading: Read off the value from the $y$ -axis where the graph crosses it; this is the number of steps Christine takes to get from her home to the track.
