The scatter plot below can be used to find the approximate rate at which water flows through a garden hose. The line of best fit for the scatter plot can be described by the equation y=54x .
If the rate, in gallons per minute, continues, approximately how many gallons of water will flow from the hose in 45 minutes?

The number of pages read by Joy depends on the number of hours she spends reading a novel.
The expression that represent the above situation is y= 20x + 3 where y represents the number of hours she spends reading and x represents the number of pages that she has read.
After reading for a total of 5 hours, the number of pages read by Joy is

Which sentence best supports the relationship shown on this scatter plot?
The more time spent training, the longer it takes to run 100 m.
As the time spent training increases, the time to run 100 m decreases.
As the time spent training decreases, the time to run 100 m decreases.
There is no apparent association between the amount of time spent training and the time it takes to run 100 m.
Julie made 25 international long-distance phone to London last month. The scatter plot below shows the length and cost of each phone call she made.
Which conclusion is best supported by the scatter plot?
As the length of the call increases, the cost of the call increases.
As the length of the call increases, the cost of the call remains the same.
As the length of the call increases, the cost of the call decreases.
There is no relationship between the length of the call and the cost of a call.
