Answer:
B. -4.8 is located below 4.8 .  TRUE
Step-by-step explanation:
The vertical line is called the Y - AXIS.
Here also, the integers are expressed as same as the horizontal axis.
.... -5, -4, -3, -2, -1 , 0 , 1 2,3 4,5 ....
In vertical line, If we move above 0, the value INCREASES.
If we move Below 0, the value DECREASES.
Now, consider the given cases:
A. -2.5 is located below -3.5 . 
Here, as -3 lies Below -2.
So, -2 > -3 ⇒  -2.5  >  -3.5
So, -2.5 is located ABOVE 3.5. 
B. -4.8 is located below 4.8 .
Here, as -4 lies Below 4.
So, 4 > -4 ⇒  4.8  >  -4.8
So, -4.8 is located BELOW 4.8.
C. 3.25 is located above 3.75 . 
Here,  3.75  > 3.25  
⇒  3.75  is located ABOVE 3.25.
D. -0.5 is located below -1.5 . 
Here, as -1.5 lies Below 0.5.
So, -0.5 > -1.5 
⇒  -0.5  is located ABOVE -1.5.
E. 0 is located below -0.87 .
Here, as  -0.87  lies Below 0.
So,0  > -0.87
⇒  0  is located ABOVE-0.87.
