12 students/1 teacher  = 276 students/x teachers
Students are on top of the ratio and teachers are on the bottom of the ratio.  It must remain the same on both sides of the equation.
12 x = 276
divide by 12
x =23
 
        
             
        
        
        
Answer:
y = -3x + 1
Step-by-step explanation:
y = -3x + 1
y = -3 . -2 + 1
 = 6 + 1
y = 7
y = -3x + 1
y = -3 . 2 + 1
 = -6 + 1
 = -5
y = -3x + 1
 = -3 . 4 + 1
 = -12 + 1
 = -11
so, it should be y = -3x + 1

<span>96-2r=6r-112
Add 2r to both sides
96=8r-112
Add 112 to both sides
208=8r
Divide 8 on both sides
