Question

the median player salary for a professional football team was $420,100 in 2000 and $1,305,528 in 2008. write a linear equation giving the median salary y in terms of the year x. (let x=0 represent 2000.)

Answer 1

`y=110678.5x+420100`

Explanation:

Given in the question that in ;

Year(x) salary y ($)

2000 420,100

2008 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

0 420,100

8 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

`(y-420100)/(x-0) =110678.5\\\\\\y-420100=110678.5(x)\\\\\\\\y=110678.5x+420100`
