Please determine the constant of each question and then write in y=kx form. Remember k=constant. Anytime you use the equation y=kx that is for a proportional table or graph.

9. Y=4x 10. Y=0.5x

Step-by-step explanation:

9. The dependent or in other words Y is inches and independent is x in this case Y is dependent so it denpends on x  since the inches rely on how much bracelts there are it means inches is y and bracelts is x. Then we do 76 divided by 19 or you can do 36 divded by 9 and both of those give us 4 which is 4 inches per a bracelet and our equation would be Y=kx or in this case Y=4x. You can check if its correct by subtituting x for 9 and if it equals 36 it means its correct.  You can also do times 19 and if it equals 76 its correct.

10.  Same proccess our x is gallons and our y is hours we can choose either one 3 divided by 6 which is 0.5 or 5.5 divided by 11 which also gives us 0.5 this proves its proporitonal and our equation would be Y=0.5 x. you can check by subtituing  x for 6 or x for 11.
