Answer:
C
Step-by-step explanation:
From the graph, you see that the point D
is ( x=4, y=-1.5 ) 
 
        
                    
             
        
        
        
1st step is to find the radius, then substitute into the formula for area of a circle 

to find the radius, just halve the diameter
 
        
        
        
Answer:
1. The y-intercept is 10
2. The slope-intercept is -2
Step-by-step explanation:
1. The y-intercept is 10 because when the x-intercept is 0 the y-intercept should be on the other side.
2.  (2,6) and (-1,12)
slope=rise/run= the change of y/the change of x=m=y2-y1/x2-x1
          1. change of x=-1-2=-3  and change of y= 12-6=6
          2. 6/-3= -2
