Answer:
y = (1/2)x - 3     Answer A is closest.  
Step-by-step explanation:
Two points on the line are (0, -3) and (4, -1).  Notice that I've intentionally chosen "nice" points whose coordinates are integers; this makes the math easier.  The point (1, -5/2) is also on the line if you want to use it, but the math's a bit more complicated.
Going from (0, -3) to (4, -1), x increases by 4 and y increases by 2.  Hence, the slope of this line is m = rise / run = 2/4, or m = 1/2.
The slope-intercept formula for the equation of a straight line is the most convenient to use here, since we can tell immediately from the graph that the y-intercept is (0, -3):
y = (1/2)x - 3
Answer A should be y = (1/2)x - 3 for improved legibility.  1 2 x is not correct as a way to express (1/2)x.
 
        
                    
             
        
        
        
Answer:
Hey there!
We have tangent 29=h/400
Thus, tangent 29 times 400=h
h=221.7 feet. 
The height of the kite  is 221.7 feet. 
Hope this helps :)
 
        
             
        
        
        
Answer:
parellel lines have same slope so slope of l2 is same as that of l1 
slope of l1 = 5-1/-2-(-3)
4/1
 
        
             
        
        
        
The answer is 80....they all have to add up to 180
