Try and read throught it slowly and everytime you hit a variable go down the the answer and find where it is. That helped me a lot
 
        
                    
             
        
        
        
<span>Write the equation of the line that satisfies the given conditions, Express the final equation in standard form. Contains the point (2,5) and is parallel to the line x-2y=-5
The given equation can be written 2y=x+5; y = (1/2)x+(5/2)
It's slope is 1/2
So any line parallel to it has slope = 1/2
If the line also passes thru (2,5), 5 = (1/2)2+b; b=4
Therefore the equation you want is y = (1/2)x+4</span>

X = nr. hrs working for a farmer;
y = nr. hrs. babysitting;
x + y <= 25;
10x + 5y >= 150
a) Solve the system => one of the solution is  x =5; y = 20(babysitting)
b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.
        
                    
             
        
        
        
Answer:
y =2
Step-by-step explanation:
Substitute -10 for x: 
2(-10)-9y = -38
-20-9y = -38
-9y = -18
9y = 18
y = 2
