For
(x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
(1,-4)
(4,2)
x1=1
y1=-4
x2=4
y2=2
slope=(2-(-4))/(4-1)=(2+4)/3=6/3=2
slope=2

Step-by-step explanation:
Given the dimension of the dog pen = 30 ft by 40 ft.
Using the knowledge of geometry, that know that a rectangle has been built, the area of the pen should be :
Area of rectangle = Length * width
Area = 40 * 30
Area = 1200 ft²
Perimeter of rectangle = 2(Length + width)
Perimeter = 2(40 + 30)
Perimeter = 2(70)
Perimeter = 140 feets
Hence, area of the pen should be 1200 ft² and its perimeter or fencing should measure 140 feets
Answer: 0.0386
Step-by-step explanation:
Number of digits = 10
Number of letters in English alphabet = 26
Total number of characters = 
Now, if replication is allowed, then the total number of ways to make a ten character password will be :_
The number of ways to make a password having all letters :-
Now, the probability that the password will contain all letters will be :-
Hence, the probability that the password will contain all letters =0.0386
