Question

A drawbridge in Jacksonville,FL, allows an average of 22 boats per day to pass. What does the point (4,88) on the graph mean in this situation

Answer 1

A drawbridge in Jacksonville,FL, allows an average of 22 boats per day to pass.

rate of change per day is 22

So equation becomes y = 22x

Here x represents the number of days

y represents the number of boats that has passed

The point (4,88) means x=4 and y = 88

x= 4 means 4 days

y = 88 means 88 boats passed

So after 4 days , 88 boats passed under the bridge.
