Question

The appropriate label for the slope of this graph is _____.

km/hr
km/hr/s
km/s
km/m

Answer 1

Hint:
the slope s of you graph is given by the subsequent ratio:
\[s = \frac{{\Delta y}}{{\Delta x}}\]
where \Delta y is measured in Km/hour, and \Delta x is mesured in seconds

Answer 2

\[\cal Slope=\rm \large\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} }\]
