Answer:
<em>Slope is -200 and y-intercept is at (0, 1200)</em>
<em>The linear equation is: </em>
<em>The value of the computer after 4.5 years will be $300.</em>
Step-by-step explanation:
Value of the new computer is $1200
For tax purposes, the linear depreciation (loss of value) is $200 per year.
So after years, total loss of value will be:
If is the declared value of the computer after years, then the linear equation will be.......
If we compare the above equation with slope-intercept form, then we will get: and
So, the slope of the line will be -200 and y-intercept will be at (0, 1200)
After 4.5 years means
So when ,
Thus, the value of the computer after 4.5 years will be $300.
