Here is my question and answer. Let me know if I am anywhere close people.
The average yearly earnings for males holding a bachelors degree is given by the linear function: f(x) = 828x + 32,134 where x is the number of years since 1996 that a person graduated.
a) Find the average earnings for males receiving a bachelor's degree in 1998
f(x)=828 (2) + 32,134
f(x)=1656 + 32,134
f(x)=33,790 average earnings
b) Predict the average earnings for males receiving a bachelor's degree in 2005
f(x)=828 (9) + 32,134
f(x)=7452 + 32,134
f(x)=39,586 average earnings
c) Predict the first year that the average earnings for a male with a bachelors degree will be greater than 50,000
50,000=828(x) +32,134
50,000-32,134=828(x)
17,866=828(x)
x=21.57
In 2018 the Average earning for a male with a bachelors degree will be greater than 50,000.
d) Find and interpret the slope of the equation.
m=828 y=mx+b
The average yearly earnings for males with a bachelors degree increases $828 dollars every 1 year.
e) Find and interpret the y-intercept of the equation.
b=32,134 y=mx+b
The average yearly earnings for males with a bachelors degree in 1996 was $32,134.
