Answer:
[tex]y=110678.5x+420100[/tex]
Step-by-step explanation:
Given in the question that in ;
Year(x) Â Â Â Â Â Â Â Â Â Â Â salary y ($)
2000 Â Â Â Â Â Â Â Â Â Â Â Â Â 420,100
2008 Â Â Â Â Â Â Â Â Â Â Â Â Â 1305528
And x=0 in 2000, then in 2008, x=8 so  you can form a table for values of x and y as
x           y
0 Â Â Â Â Â Â Â Â Â Â 420,100
8 Â Â Â Â Â Â Â Â Â Â 1305528
To come up with a linear equation, you need to find the slope,m
m=change in y values/change is x values
m=(1305528-420100)÷ (8-0)
m=885428/8 =110678.5
To find the equation
Δy values ÷ Δx values =m
Δy values=y-420,100
Δx values= x-0
m=110,678.5
[tex]\frac{y-420100}{x-0} =110678.5\\\\\\y-420100=110678.5(x)\\\\\\\\y=110678.5x+420100[/tex]
