Answer:
Step-by-step explanation:
The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.
Thus, gradient of given line=.
The product of the gradients of perpendicular lines is -1.
(Gradient of line)(-3/2)= -1
Gradient of line
Substitute m= into y=mx+c:
To find the value of c, substitute a pair of coordinates.
When x= -6, y= 8,
Thus, the equation of the line is .
Answer: The number of different passwords can be formed = 1,000,000
Step-by-step explanation:
In general total digits = 10 [ from 0 to 9]
If a password contains 6 digits, then by fundamental principal of counting, the total number of different passwords =
Hence, the number of different passwords can be formed = 1,000,000
