You can put this solution on YOUR website!
the distance (d) you bike varies directly with the amount of time (t) you bike.
suppose you bike 13.2 mi in 1.25 hours.
what is an equation that relates d and t? what is the graph of this equation?
:
Since we are starting from the origin (0,0), we can determine the slope to be13.2%2F1.25,
hence the equation:
d = 13.2%2F1.25t
looks like this
+graph%28+300%2C+200%2C+-4%2C+10%2C+-10%2C+80%2C+%2813.2%2F1.25%29x%2C+13.2%29+
You can see when t = 1.25 hrs, d = 13.2 mi (green line),
