Answer:
1. y =  x +
x + 
2. Divide the Opposite of A and B
3. Doesn't make sense the y-intercept is C/By sry I can't help that one
Step-by-step explanation:
1. Ax + By = C
By = -Ax + C
y =  x +
x + 
 
2. No explanation

In order to reduce ANY fraction to lowest terms, find any common factors 
of the numerator and denominator, and divide them both by it.  If they still 
have a common factor, then divide them by it again.  Eventually, they won't 
have any common factor except ' 1 ', and then you'll know that the fraction is 
in lowest terms.
Do  15  and  40  have any common factors ?
Let's see . . .
The factors of  15  are  1,  3,  <em>5</em>, and  15 .
The factors of  40  are  1,  2,  4,<em>  5</em>,  8,  10,  20, and  40 .
Ah hah !  Do you see that ' <em>5</em> ' on both lists ?  That's a common factor.
So  15/40  is NOT in lowest terms.
Divide the numerator and denominator both by  5 :
       15 / 40  =<em>  3 / 8</em>
3  and  8  don't have any common factor except ' 1 '.  
So  3/8  is the same number as  15/40, but in lowest terms.
        
                    
             
        
        
        
Move the 14 over and get
5x = 2
divide by 5
x = 2/5
