On a recent day 8 euros were worth 9 and 24 euros were worth
     On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.  where y is dollars and x is euros  The graph shows the number of servings in different amounts of frozen yogurt listed on a carton. Write an equation that gives the number of servings y in x pints.  A refreshment stand makes 2 large servings of frozen yogurt from 3 pints. Add the line to the graph and write its equation.  How can you use rates to determine whether a situation is a proportional relationship? 
  
  Solution
Answers to this question:
6. The relation of Euro to Dollar is
Euro = 3* Dollar
 x = 3y, x = Euro and y = Dollar
7.y =2.5x is the equation of line.
 To get the slope simply take 2 points on the line and caclcualte the slope.
8. The \"dot\" on the graph is the right representation of this
 question
9. Many ways: Correlation, linear regression, linear slope.
