Answer:
The point (8, 4) on the graph represent that: 
'Every 8 Minutes, 4 Pictures are Taken.'
Step-by-step explanation:
Since the graph has not been provided lets try to explain in actual context. 
The question states that the Graph shows the <u>Number of Pictures</u> a traffic camera takes <u>Each Minute.</u> 
This tells us that we have a two-dimensional graph, of  with
 with  where:
 where:
 : denotes <em>Each Minute</em>
: denotes <em>Each Minute</em>
 : denotes <em>Number of Pictures taken</em>
: denotes <em>Number of Pictures taken</em>
<em />
<em>Thus  is our </em><u><em>independent </em></u><em>variable that changes, and as a result of it so does
 is our </em><u><em>independent </em></u><em>variable that changes, and as a result of it so does  , our </em><u><em>dependent </em></u><em>variable. </em>
, our </em><u><em>dependent </em></u><em>variable. </em>
As such we can conclude that any point from the graph is of the form 
 .
. 
Here the question asks what does the point  represent. So based on the information above we know that here:
 represent. So based on the information above we know that here:
 and
 and 
which if read on the graph it would indicate that:
On the x-axis of minutes we are looking at minute 8 and on the y-axis of number of pictures taking we are looking at the value 4. Thus:
 represents that Every 8 Minutes, 4 Pictures are Taken.
 represents that Every 8 Minutes, 4 Pictures are Taken.
