A is (2, -1)
The X axis will not change since A is not going left or right of (2,2). You would count down 3 spaces for the y-axis and that would land you at -1 or you could solve by subtraction.
2-3= -1
Answer:
Firstly you need to put the equation in form of. y =ax+b
Let us do it
We have
2x-2y=18
-2y=18-2x
-y=(18) /2 - (2x)/2
-y =9-x
Mutiply by - to remove it beside y
Y=-9+x
Which is y=x-9
Slope =a=1
Yintercept=b=-9
144 square inches because it's 12 by 12 by 12
Year 1: 1,300 * 55% = 715 depreciation
1,300 - 715 = 585 book value
Year 2: 585 * 55% = 321.75 depreciation
585 - 321.75 = 263.25 book value
Year 3: 263.25 * 55% = 144.79 depreciation
263.25 - 144.79 = 118.46 book value
If the bike was bought 2 years ago, then its current value is $263.25.
Currently, it is the beginning of Year 3 but depreciation is computed at the end of the year.
