The initial cost of an office fax machine is $100. After 1 year, its value becomes $80. Which is the correct linear depreciation
Elis [28]

Answer:

y=100-20x

Step-by-step explanation:

Let the x-axis be the time (in years) and the y-axis the value of the fax machine (in dollars).

We know that the initial value of the fax machine is $100; in other words, when the time is zero years, the value is $100, or as an ordered pair (0, 100). We also know that after 1 year the value decreases to $80, so (1, 80).

Now we can find the slope of the line passing through those two points using the slope formula

m=\frac{y_2-y_1}{x_2-x_1}

where

m is the slope

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

Replacing values:

m=\frac{80-100}{1-0}

m=-20

Now, to complete our model we are using the point slope formula

y-y_1=m(x-x_1)

where

m is the slope

(x_1,y_1) are the coordinates of the first point

Replacing values:

y-100=-20(x-0)

y-100=-20x

y=-20x+100

y=100-20x

We can conclude that the correct linear depreciation model is y=100-20x
