Point slope equation: 
y-y1=m(x-x1) 
m=slope
So we simply plug in our given information: 
x1=-8 
y1=2
m=1/2
y-2=1/2(x-(-8)  
2 minus signs next to each other make a positive 
Final answer: 
y-2=1/2(x+8)
        
             
        
        
        
Answer:
The height of the tree is H = 77.06 m 
Step-by-step explanation:
From Δ ABC 
AB = height of the tree

 
 
h = 0.9623 x ------- (1)
From Δ ABD

h = 0.77 (x + 20) ----- (2)
Equating Equation  1 & 2 we get
0.9623 x =  0.77 (x + 20)
0.9623 x = 0.77 x + 15.4
x (0.1923) = 15.4
x = 80.08 m
Thus the height of the tree is given by
H = 0.9623 x
H = 0.9623 × 80.08
H = 77.06 m
Therefore the height of the tree is H = 77.06 m 
 
        
             
        
        
        
The answer is false, it is only true for postulates, not conjectures.
        
                    
             
        
        
        
X = 3 y = 4
so answer is 4
