Answer: y = 
+ 2.5
Step-by-step explanation:
The formula for finding the equation is given as :
= 
From the points given:
= 7
=-1
= 6
= 2
Substituting into the formula , we have:
= 
= 
= 
2(y-6) = x -7
2y - 12 = x -7
2y = x - 7 + 12
2y = x + 5
y = + 
y = + 2.5

Answer: 6
Hope this helps!
The first thing to do is find the rectangular warehouse area.
We have then:
A = (12) * (18) = 216
A = 216 m ^ 2
We now look for the area of each acoustic tile square:
A '= (1) ^ 2 = 1
A '= 1 m ^ 2
We look for acoustic tile squares number:
N = (A) / (A ')
N = (216) / (1)
N = 216
Finally we look for the total weight:
W = (1/4) * (216)
W = 54 Kg
Answer:
The total weight of the tile required to cover the ceiling is:
W = 54 Kg
