I hope this helps you 
x^2+2x+8=0
x^2+2x+1+7=0
(x+1)^2= -7
(x+1)^2= i^2.7
x+1= i.square root of 7
x=-1+ i.square root of 7
        
             
        
        
        
Answer:
The correct answer is D. The points are rotated 180 degrees and scaled by a factor of 0.5.  I assume that the 0.5 is the expected value in the text box labelled "D" (for dilation perhaps?)
 
        
             
        
        
        
<span>Hello : let
 A(-3,7)    B(3,3)
the slope is :   (YB - YA)/(XB -XA)
(3-7)/(3+3)  = -2/3
an equation is : y=ax+b     a is a slope</span>
y = (-2/3)x +b
 
the line through point B (3,3) :
 3 = (-2/3)(3)+b<span>
<span>b =5 
the equation is : y =(-2/3)x+5</span></span>
 
        
             
        
        
        
I don't think it can be reduced anymore.
