On a recent day, 8 euros were worth $9 and 24 euros were worth 27.

This question is incomplete, here is the complete question: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.The equation that represents the relationship between the number of euros and the value in dollars is y = 1.125 xStep-by-step explanation:On a resent day;8 euros were worth $924 euros were worth $27We need to write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars∵ The form of the equation is y = kx, where x is the number of    euros and y is the value in dollars∵  8 euros were worth $9∴ (8 , 9) is an ordered pair belong to the equation∵ 24 euros were worth $27∴ (24 , 27) is another ordered pair belong to the equationTo find k substitute x and y in the equation by the coordinates of one of these two points∵ x = 8 and y = 9∵ y = kx∴ 9 = 8k- Divide both sides by 8∴ 1.125 = k- Substitute the value of k in the equation∴ y = 1.125 xTo check the equation substitute x by the x coordinate of the 2nd point if it gives the same value of the y-coordinate of the point then the equation is true∵ x = 24 ∵ y = 1.125 x∴ y = 1.125(24) ∴ y = 27 the same value of the y-coordinate of the point ∴ The equation is trueThe equation that represents the relationship between the number of euros and the value in dollars is y = 1.125 xLearn more:You can learn more about the linear equation in brainly.com/question/4326955#LearnwithBrainly
