## Calculus: Early Transcendentals (2nd Edition)

The slope of the secant line: m$=2$ represents the average velocity of the object over the time interval $[0,0.5]$.
Graph s(t) by building a table of function values. Plot the points and draw a smooth curve through them. See image. The slope of the secant line: m= $\displaystyle \frac{s(0.5)-s(0)}{0.5-0}= \displaystyle \frac{1}{0.5}=2$. This represents the average velocity of the object over the time interval $[0,0.5]$.
