Yelania and audrey are playing the integer game. below art the two cards they selected. remember, in the integer game, the numbers on their cards are added to find the sum. how do the models for these two addition problems differ on a number line? how are they the same? they are different: they are the same:

The models are different.

Step-by-step explanation:

Yelania and Audrey took two cards which are 4,-6 and 4,6 respectively.

They do not lie on the same points as the sum of Yelania's cards=4-6=-2 and the sum of Audrey's cards=4+6=10.

Both -2 and 10 lie differently on the number line.

Therefore, the models are different from each other.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
