Step-by-step explanation:
Given expression;
    2x + y  = -5;
   The given equation must be written in a form where the slope is the negative inverse of the given one. 
A line perpendicular to another will have a negative inverse slope. 
    2x + y  = -5 
   Equation of a straight line is generally written as; 
        y  = mx + c 
y and x are the coordinates 
m is the slope 
c is y - intercept
           2x + y  = -5 
                  y  = -2x -5
  The slope of the perpendicular =  
 
So, 
the new line;
             y  =   x  -5
x  -5
Any line with slope of   will be perpendicular
 will be perpendicular
 
        
             
        
        
        
Answer:
Below in bold.
Step-by-step explanation:
4x + y = 9
Let's put x = 0 then:
4(0) + y = 9
0 + y = 9
y = 9
So one. ordered pair that is a solution is (0, 9)
 
        
             
        
        
        
To get the answer, you will just use this operation: Division.
Let's divide it. 81 ÷ 13.5 = 6.
So, the answer is
