Answer:
Let X represent Nick's age and Y represent Sara's age.
Then, it is given that: Nick is four years older than Sara.
We write the statement as:
or 
The only ordered pairs (X,Y) which satisfy the equation are: (0,-4) and (4,0) as you can see in the graph also.
In the graph X axis represents the age of Nick's age and Y-axis represent the age of Sara's age and the line Y=X-4 represents the relationship between the age of both.
Remember that A squared plus B squared equals C squared.
Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.
SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.
3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18
You get the idea. Hope this helps!
Answer:
domain:

range:
![( - \infty ,4]](https://tex.z-dn.net/?f=%28%20-%20%20%5Cinfty%20%2C4%5D)
equation:

Step-by-step explanation:
domain is all X values and the X values will extent till infinity in both negative and positive direction, the range is all y values and the y value will go from negative infinity all the way to 4, where the graph stops.
