Answer:  d) 14
Step-by-step explanation:
Equation of a line passing through (a,b) and (c,d):

Equation of a line passing through (2, 18) and (–3, 8):

Comparing resulting equation  to
 to  , we get value of b= 14.
, we get value of b= 14.
Hence, correct option is  d) 14
 
        
                    
             
        
        
        
Answer:
x = -16 
 
Step-by-step explanation:
When there are two lines that intersect at one point, the two angles that are directly opposite each other are equal. So in this case, (6x+175) = (3x + 127) 
6x + 175 = 3x + 125
6x - 3x = 125 - 175
3x = -50
x = -50 ÷ 3
x = -16 
 
 
        
                    
             
        
        
        
-3 times -3=9
9-(-3)=9+3
9+3=12
