**4.**

**A)**

An example of a linear relationship in real life is

how much oranges a basket can hold. For example to get to 1 basket full you would need 5 oranges.

Another example with out context is the x axis going up by ones starting at 1. then the Y axis going up by 3 starting at 3

**B)**

**C)**

**One with Context**

**One without Context**

**D)**

**Some Similar things are both of them a x and y axis. Also both graphs have a linear relation ship and both graphs have also the same pattern going on on x and y axis's. Some Differences are that one is label and the other one is not and the one with out context goes up by 3 each time while the one with context goes up by 5 each time.**

**7.**

**A)**

**When**

*x*is equal to 65x - 3 = y

5(6) - 3 = y

30 - 3 = y

27 = y

**B)**

**When**

*x*is equal 5x - 8 = y

(5) - 8 = y

(-3) = y

**C)**

**When**

*x*is equal to (-2)-5x = y

-5(-2) = y

10 = y

**D)**

**When**

*y**is equal 25*x = y

x = 25

**10.**

**A)**

**2x = y**

**B)**

**3x - 1 = y**

**C)**

**-4x + 5 = y**

**D)**

**5 - x = y**

**13.**

**A)**

**B)**

**Yes because you can graph decimals and also graph numbers even if the number is not there. Meaning if you look at the graph there is no one but if you put it in the middle of 0 and 2 it is indicating that the point must be one. but if you have a point between 0 and 1 it must be indicating that it must be a decimal.**
