it can't be determined

Every sum x + y is the same for related pairs of x and y.

Every x term is multiple of the previous term

Every difference x - y is the same for related pairs of x and y

Every ratio of y/x for related pairs of x and y is equivalent

You really have no way of knowing. It's a messed up world.

Yes the difference between each x and y value is the same.

No, all ratios of x/y are greater than 1.

No all the ratios of y/x are not equivalent.

Yes, as each x increases by 1 each y value increases by $1.75

x = 6, y = 5

x = 4, y = 5

x = 5, y = 6

The relationship is not proportional because the graph does not pass through the origin.

The relationship is proportional because as time increases the diameter of the tree also increases.

The relationship is not proportional because the graph is not a straight line.

The relationship is proportional because the graph is a straight line.

This table DOES show a proportional relationship between the number of guests and the number of cookies.

This table DOES NOT show a proportional relationship between the number of guests and the number of cookies.

It impossible to determine if this is proportional because we don't know how many guests will arrive.

It doesn't really matter because Cookie Monster will show up and eat all the cookies anyway!

The table DOES show a proportional relationship between months and amount in saving account.

The table DOES NOT show a proportional relationship between months and amount in saving account.

Your friend needs to get a calculator and learn how to use it.

C.O.P. =12.6, I have no idea why it's called that.

1.26 It's called that because it sounds complicated and mathematicians are always trying to make these complicated!

C.O.P. = 12.6, Its called the COP because 12.6 is the constant multiple of x that gives you y.

I have never heard of this. I think you are messing with us, Mrs. Schlottman!

 $y^2\ =$  y  $\times$   y

y $\div$  x is the constant of proportionality and the unit rate. Once you find it just plug it into y = kx and you have this sweet equation. A graph of a proportional relationship is always a straight line that goes through the origin.

There is no point to math. It's just hard and I will never learn any of it. I am going to work at McDonald's and live in my parents basement when I am 40  years old.

The main point is to torture me with math formulas.

Doing Math, baby!

Anything that involves math! Because I will make a lot of money someday if I learn how to do math like a boss!
