median salary for a professional football team was $436,000 in 2000 and $1,321,348 in 2008. Write a linear equation giving the median salary y in terms of the year x. (Let x = 0 represent 2000.)

Answer 1

first create two points

2000 (0, 436000)

2008 (8, 1321348)

now solve like an algebra problem

Slope = 1321348-436000 = 885346/8

slope = 110668.50

so the complete linear equation would be

y = 110668.50 x + b

where x is the number of years after 2000 (ex 2010 would be 10)
