Answer: -1/9
Step-by-step explanation:
Find the Slope  (−3, 2) and (6, 1)
Slope is equal to the change in y over the change in x, or rise over run.

The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
     
Substitute in the values of x and y into the equation to find the slope.
     
Simplify the numerator. Tap for more steps...
      
Simplify the denominator.
      
 
        
                    
             
        
        
        
We have the following expression given:

We can start selecting as common factor 4y^2 and we got:

Now we can select y+7 as common factor and we got:

So then our final answer would be:

-----------------------------------------
Define x :
-----------------------------------------
Let the smallest number be x.
The other two numbers will be x + 1 and x + 2.
-----------------------------------------
Construct Equation :
-----------------------------------------
Sum of these numbers is 72
⇒ x + x + 1 + x + 2 = 72
-----------------------------------------
Solve for x :
-----------------------------------------
x + x + 1 + x + 2 = 72
3x + 3 = 72
3x = 69
x = 23
-----------------------------------------
Find the numbers :
-----------------------------------------
1st number = x = 23
2nd number = x + 1 = 23 + 1 = 24
3rd number = x + 2 = 23 + 2 = 25
----------------------------------------------------------------------------------
Answer : The numbers are 23, 24 and 25.
