Question

The median player salary for a professional football team was $430700 in 2000 and $1316208 in 2008. Write a linear equation giving the median salary y in terms of the year x. (Let x=0 represent 2000)

Answer 1

So the graph would look like this:

To find the slope, subtract the two y-values and subtract the two x-vales and divide (m = (y₂ - y₁)/(x₂ - x₁)

m = (1316208 - 430700)/(2008 - 2000) = 885508/8 = 110688.5

The y-intercept (the "b" in "y = mx + b") is 430700.

Plug these into y = mx + b
