To calculate the slope containing two points, we can use that formula:
"m" represents the slope and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is 2 uc.
19 feet
convert 2
into an improper fraction
2
= 
hence the length of the wall is 19 feet
Answer:
P= 221cm
