You can find the slope of a linear function by taking two points and finding the change in y over change in x.
Hm, but the values you gave for the tables don't make sense for a linear function/relationship. But let's just pick two points as an example.
So two points you can pick are (-2, 13) and (1, -3).
The slope, change in y over change in x is in other words (y2 - y1 / x2 - x1), where (x1, y1) is one point and (x2, y2) is another.
(-3 - 13) / (1 - -2) = -16/3 = -(16/3)
Or you could have switched up the order of those coordinates but you still get the same answer.
(13 - -3) / (-2 - 1) = 16 / (-3) = -(16/3)

Answer:
The computer will be worth $1,850 after four years.
Step-by-step explanation:
We need to find 6.5% of $2,500.
2,500 x 0.065 = $162.50
Therefore, the computer value <em>decreases</em> by $162.50 <u>each year</u>. Since we need to know the computer value after <u>4 years</u>, we also need to<em> multiply </em>the value of decrease by 4.
162.5 x 4 = $650
Therefore, after 4 years, the computer value <em><u>will decrease</u></em> by $650.
To find the <em>whole</em> computer value after 4 years, we need to <em>subtract</em> the initial value of $2,500 by the 4-year decreasing value of $650.
2,500 - 650 = $1850
Therefore, the computer will be worth $1,850 after four years.
Hope this helps! :D
