A bottle of water cost $1.50 explain how you would make a graph of four ordered pairs to model the total cost of the water in terms of the number of bottles

Answer:The graph in the attached figuresee the explanationStep-by-step explanation:Letx -----> the number of bottlesy ----> the total cost of the water we know thatA relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]This problem represent a direct (proportional) variation soFor x=1, y=$1.50[tex]k=y/x[/tex] -----> [tex]k=1.50/1=1.50[/tex]The linear equation is equal to[tex]y=1.50x[/tex]Find the ordered pairsFirst(1,1.50)SecondFor x=2Find the value of ySubstitute in the equationy=1.50(2)=3The point is (2,3.00)ThirdFor x=3Find the value of ySubstitute in the equationy=1.50(3)=4.50The point is (3,4.50)FourthFor x=4Find the value of ySubstitute in the equationy=1.50(4)=6.00The point is (4,6.00)The four ordered pairs are(1,1.50), (2,3.00),(3,4.50) and  (4,6.00)using a graphing toolplot the points
