To find the slope (m), use the slope formula:
 and plug in the two points
         and plug in the two points
(4, -4) = (x₁, y₁)
(6, -6) = (x₂, y₂)
[lines usually go from left to right, so the point furthest to the left is the 1st point]

 [two negative signs cancel each other out and become positive]
   [two negative signs cancel each other out and become positive]


m = -1
 
        
             
        
        
        
4,550 is the answer when you multiply the two numbers together.
        
             
        
        
        
Answer:
