The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. 
 
        
             
        
        
        
The correct answer to this question is 9. This can be worked out due to
the fact that 1/10 of 900 is 90, so to reach 90 you have to times 9 by
10.
        
             
        
        
        
Equation of the perpendicular
y= 2x+6
slope of the perpendicular = 2
slope of the req. line = -1/2
equation of the req. line
y - y1 = m(x - x1)
y - 2 = -1/2(x + 4)
2(y - 2) = -1(x + 4)
2y - 4 = -x - 4
2y = -x
y  = (-1/2)x
this is your req. equation of line.
        
             
        
        
        
Answer:
   c = 92/n
Step-by-step explanation:
The equation that describes the inversly proportional relationship is ...
   y = k/x
The value of the constant of proportionality can be found from ...
   xy = k . . . . . . product of values of independent and dependent variables
__
In this problem, we have c = 23 for n = 4, so the constant of proportionality is ...
   k = c×n = (23)(4) = 92
The equation for the relationship is ...
   c = 92/n
