Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10
meters past the starting line. Chana skated 3 meters per second and Josiah skated 2 meters per second.
Here's a graph that shows a system of equations for this scenario where is the number of seconds since
Chana and Josiah started skating and y is the distance in meters from the starting line.

What does point F represent in this context?
