SWIMMING Yukio is keeping track of the number of calories she
burns while swimming freestyle laps. The number of calories she
burns can be represented by a function. Sketch a graph that shows
the number of calories burned y as a function of time x, in hours.
y-Intercept: No calories burned when she has swum for 0 hours.
Linear or Nonlinear: The graph of the function is linear.
Positive: for time greater than 0
Increasing: for time greater than 0
End Behavior: As the number of hours she has swum increases, the
number of calories burned increases.
