Answer:

The farthest point is the Challenger Deep
Step-by-step explanation:
Given


Solving (a): The sea level
Both elevations had signs in front of them.
The sea level is the point at the neutral level, neither positive nor negative.
Hence:

Solving (b): Farthest Point.
The farthest point is the one with the highest magnitude.
Comparing
to 
-35,797 ft has the highest magnitude.
Hence:
<em>The farthest point is the Challenger Deep</em>
The slope of this line is the difference of the y values divided by the difference of the x values. Solving this give 4/-3. Then, you already know the b in y = mx+b, which is 2, because you already have the value (0, 2). So, the answer is y =
x + 2
Answer:

Step-by-step explanation:
-This is an addition/subtraction problem.
#We subtract the sum of the first two expression from the third expression:

Hence, the expression
must be added to the first two.
