Step-by-step explanation:
0.9 / 10^3 = 0.0009
 
        
             
        
        
        
Step-by-step explanation:
First, sub in the ordered pair to find y int
(7) = -1(-2) + b 
7 = 2 + b
b = 5
So the equation in y int form is 
y = -1x + 5 
This when convert to stardard form is 
x + y = 5 
 
        
             
        
        
        
Answer:
y =  x + 7
 x + 7
Step-by-step explanation:
Given
x = 3t ( divide both sides by 3 )
 x = t
 x = t
Substitute this value into y = 2t + 7
y = 2 ×  x + 7 =
 x + 7 =  x + 7
 x + 7
