Answer:
 <em>y = - 4x + 5 </em>
Step-by-step explanation:
y = mx + b 
(0, b) y-intercept 
m =  
 
~~~~~~~~~~ 
( - 2, 13) 
(0, <em>5</em>) <----- y-intercept 
(3, - 7) 
(4, - 11) 
<em>m =</em>  = <em>- 4</em>
 = <em>- 4</em> 
<em>y = - 4x + 5</em> 
 
        
             
        
        
        
7-3=4
9-2=7
4x7=28
Use PEMDAS for order of operations, it will save your life
Parenthesis Exponents Multiply Divide Add Subtract
Multiply and Divide  and  Add and Subtract can be switched around with each other, but multiply and divide always happens before add and subtract. The reason you add first here is because it is in the parenthesis.
        
             
        
        
        
The answer is 60x-52y

The answer is 36. because 12x3=36, 9x4=36, and 4x9=36, so it is the least common denominator
