(0,2)and (3,-2)
slope = (2+2)/(0-3) = -4/3
y intercept b = 2
equation
y = -4/3 x + 2
Answer is A
y = -4/3 x + 2
        
                    
             
        
        
        
(86 + 70 + 79 + 90 + 85 + x)/6 = 84
Multiply 6 to both sides and then add everything together and then subtract i from the multiplied 86 which will get you 94. 
Answer: 94
        
             
        
        
        
-1 is less than 0, so you use the first equation:
3(-1) +2 = -3+2 = -1
f(-1) = -1
For 0 use the 2nd equation:
3(0) + 4 = 0+4 = 4
f(0) = 4
For 2 use the 2nd equation:
3(2) + 4 = 6+4 = 10
f(2) = 10
 
        
             
        
        
        
C.416 
You take 312 and 6 then divide (312/6) which gives you 52. Then take 52 and 8 and multiply 52×8= 416
        
                    
             
        
        
        
Sure. So the hundreds digit is after the tens digit which is 3, so therefore it's 4. The millions digit is 7 places to the left, so it's 7. Ten thousands digits are 5 places to the left, so it's 9. The hundred thousands is 6 to the left, therefore 8. Finally, the thousands is 4 places to the left, so it's 0. Hope this helped!
