As a math teacher, Josie frequently makes photocopies of fun activities for her students to do When the coples come out of the copy machine, they form a stack. This table shows the relationship between the number of copies in the stack, x, and the height (in millimeters) of the stack, y. x (copies) y (millimeters) According to the values in the table, do x and y have a proportional relationship? yes no​

Answer 1

Yes.

10y = x

or x / 10 = y

or x / y = 10

Explanation:

20 / 2 = 10

50 / 5 = 10

60 / 6 = 10

70 / 7 = 10

Answer 2

Yes x and y do have a proportional relationship because with every 10 copies of paper the value of y goes up by 1 meaning that it would have a constant rate of change equal to 1/10
