Answer:
1 y=-1/10x
2 y=-x-8
3 y= 7/3x or 2 1/3x
Step-by-step explanation:
1 -x=10y
divide -x and 10 by 10
2 y+8=-x
subtract 8 
3 -4+7x+4=3y
divide everything by 3
 
        
             
        
        
        
...6 and 10 are roots, so x – 6 and x – 10 are factors. 
 y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a: 
 2 = a(8 – 6)(8 – 10) 
 2 = –4a 
 a = –1/2 
 ...y = (–1/2)(x – 6)(x – 10) 
 ...y = (–1/2)(x² – 16x + 60) 
 ...y = (–x²/2) + 8x – 30 <<<------Answer, or: 
 ...y = (–1/2)(x – 8)² + 2 <<<------Answer
