Answer:
for the first one I got y=-2x-2 the second part i got y=-x-1 or -1x-y-1=0  Correct me if I am wrong 
Step-by-step explanation:
Use the slope formula 
-4-4 =-8
   /               =-2
1 - -3=4
2. The second part use this formula y-y1=m(x-x1)
      y--4=-1(x-3)
y+4=-x+3
   -4      -4
y+0=-x-1
  y=-x-1      or -1x-y-1=0    I am not sure   
 
        
             
        
        
        
First one is 3/8>1/3
Second one is B
Third one is C
Fourth one is B
        
             
        
        
        
Answer:
option A is correct answer
divide both sides with 2

Equilateral Triangle - all sides equal and all angles equal
 Isosceles Triangle - two sides equal andtwo angles equal
Scalene Triangle - no sides equal and no angles equal
so
1-6 a)
Isosceles Triangle - 1 Line of Symmetry
1-6b)
Equilateral Triangle-  3 Lines of Symmetry 
1-6 c)
