Answer:
The correct option is 2.
Step-by-step explanation:
The slope of two parallel lines are equal.
The slope intercept form of a line is
Where, m is slope and b is y-intercept.
In option 1, the equation of lines are
The first line is a horizontal line and the second line is a vertical line. Therefore they are not parallel line. Option 1 is incorrect.
In option 2, the equation of lines are
By using the slope intercept form of a line, the slope of first line is 4 and the slope of second line is 4.
Since the slope of both lines are same, therefore both lines are parallel. Option 2 is correct.
In option 2, the equation of lines are
By using the slope intercept form of a line, the slope of first line is 5 and the slope of second line is -5.
Since the slope of both lines are not same, therefore both lines are not parallel. Option 3 is incorrect.
Answer:
Rate of depreciation per year is 4310 $/ year and the depreciation schedule is given below.
Step-by-step explanation:
According to the question,
since, it is straight-line depreciation,
rate of depreciation per year = $/year
= 4310 $/ year
So we can prepare the following table. (year = 0 for the base period)
Year Depreciation Accumulated Book value
expense depreciation
( in $) (in $) (in $)
