The table lists data regarding the average salaries of several professional athletes in the years 1991 and 2001.

year average salary
1991 $263,000
2001 $1,430,000

a)Use the data points to find a linear function that fits the data.

b) Use the function to predict the average salary in 2005 and 2010


Could someone please check my answers
a)S(x)=116,700x+146,300

b) in 2005 $1,780,100
in 2010 $2,363,600

  • math -

    no, if you are going to use the actual year for the value of x, I got
    S(x) = 116700x - 232086700

    then for 2005
    S(2005) = 116700(2005) - 232086700
    = 1896800

    and S(2010) = 116700(2010) - 232086700
    = 2480300

    btw, the two given ordered pairs satisfy my equation
