Linear Relationships Practice Quiz

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  $y=\frac{4}{5}x$  .

If the rate, in gallons per minute, continues, approximately how many gallons of water will flow from the hose in 45  minutes?
