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 x is the number of seconds since Chana
and Josiah started skating and y is the distance in meters
from the starting line.
y (distance)
line b: y = 32
60+
line a : y = 10 + 23
