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: Choice A. 8pi  feet</h3>
======================================================
Explanation:
The perimeter around the circle is known as the circumference
The full circumference of a circle with radius r is 
C = 2*pi*r
In this case, r = 16 is the radius, so,
C = 2*pi*r
C = 2*pi*16
C = 2*16*pi
C = 32pi
is the full distance around the circle. But we only want 90/360 = 1/4 of that total distance. So take 1/4 of 32pi to get 
(1/4)*32pi = (1/4*32)pi = 8pi
The arc length is exactly 8pi feet long
Approximately this is about 25.13274 feet
 
        
                    
             
        
        
        
Answer:84.8
Step-by-step explanation:
 
        
             
        
        
        
The first one is correct because the angle on the opposite side is the same, and the second one is correct too because it's the same points.  So you can pick either or.
