Answer:
(12,0), (3, -1) (0,-4/3)
Step-by-step explanation:
To do this problem, you have to plug in the x and y values. For example, the first one would be 12-9(0)=12, and so on.
 
        
             
        
        
        
Change the equation to slope intercept form: 
-5y=-x+10
y=1/5x-2
The y intercept is -2

Answer:  
1st Question
A. 85
2nd Question  
B. 71
Step-by-step explanation:
1st Question
{90 + 94 + 96 + 90} = 370/4 = 92.5
{95 + 99}                  = 194/2 = 97
{87 + 75 + 82 + 85} = 329/4 = 82.25
{71}                =  71/1               = 71
.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175  Rounded-up = 85

2nd Question  
.10(95) +.20(80) +.50(67) +.20(60) = 71
