Hello : 
<span>the y-intercept of y = -4/3x + 4 when x=0 : y= (-4/3)(0)+4=4
Answer : </span><span>A) (0, 4)</span>
        
             
        
        
        
Use a= 

r^2 (r represents your radius of 4 feet)

(4^2)
Answer = 16

^2
 
        
        
        
Answer:
d
Step-by-step explanation:
because it's the same number
 
        
             
        
        
        
The slope is negative as it slopes to the left
using the extremities of the line:-
-(10+10 / (10 + 10)  = -1
slope is -1.
        
                    
             
        
        
        
Answer:
y = -x + 9.
Step-by-step explanation:
The slope = rise run
= 9 /-9
= -1.
The y intercept is at y = 9 so the equation is:
y = -x + 9.
