Answer:
The other coordinate is (-6,19)
Step-by-step explanation:

(4,-7)
(x,y)
[(4+x)/2 , (-7+y)/2] = (-1,6)
(4 + x)/2 = -1
 4 + x = -2
 × = -6
(-7 + y)/2 = 6
 -7 + y = 12
 y = 19

An isotherm on a geographic map is a type of
equal temperature at a given date or time. And if we talk about thermodynamics,
it is a curve on a Pressure – Volume diagram at a constant temperature. 
 
Basing from the graph, we can actually see that
the interval is:
 
10 <span>Fahrenheit degrees</span>

Step-by-step explanation:
V=a²h/3
=9² x 4/3
= 81 x 4/3
= 27 x 4 
= 108 cm³
 
        
             
        
        
        
Neither of the equations are parallel or perpendicular
