Broken down into steps:
1.  Find the slope of the line segment that connecs the points (0,-7) and (4,-15).
2.  Start with the point-slope formula for the equation of a straight line:
y-b = m(x-a), where the given point is (a,b).  Borrow the value of m that you calculated in (1), above, and insert it into this point-slope formula.
Finish up by subst. the x- and y-values in (-3,6) into this formula.
Done!
You could, of course, solve this result for y if you wished.
        
             
        
        
        
Answer:
-3,8 -2,10 2,9 1,3
Step-by-step explanation:
add two to the y and seven to x
 
        
                    
             
        
        
        
C is irrational because there is no definite square root for 15 whereas the square root of 36=6
        
                    
             
        
        
        
The perimeter is 166.9 ft.
Convert feet to inches to make it easier to calculate. The formula to find the perimeter is... 2(w+h)
once you get your answer, convert inches back to feet.
 
        
             
        
        
        
I think its 28 because 308 divided by 11 is 28 to find how many gallons were used per mile
