Answer:
The equation of the line is:  y = x + 4
Step-by-step explanation:
When we are given two points passing through a line, we can find the equation of the line by using two - point form.
Two - point form:    
where  are the points passing through the line.
 are the points passing through the line.
Here, let us take two points (can be any two): 
 and
 and 

Therefore, we have:

Answer:
DE = 13.4 cm  (to 1 decimal place)
Step-by-step explanation:
Given: ABCD is a square
BC = AC = 12 cm    (opposite sides of a square are congruent)
E is midpoint of BC   (given)
BE = EC  = 12/2 = 6 cm
CD = AB = 12 cm   (opposite sides of a square are congruent)
angle ECD is a right angle (interior angles of a square are 90 deg.)
Consider right triangle ECD
DE = sqrt(EC^2+CD^2)    ............. pythagorean theorem
= sqrt(6^2+12^2)
= sqrt ( 36+144 )
= sqrt (180)
= 2 sqrt(45) 
= 13.416 (to three dec. places)
 
        
                    
             
        
        
        
 How man bags were used?
41 / 3 = 13.7
We can say about 14 bags by rounding to the nearest whole number. Therefore, 14 bags were used.
