Question 1193676: Average starting salaries for students majoring in business have been increasing. The equation which predict average starting salary is
S = 20,250 + 1,050t
where s equals average starting salary and t is time measured in years since 1990 (t = 0). a. Identify s and t intercepts for this cquation.
b. Interpret these values where they are meaningful.

The -intercept is meaningless because it would represent a time prior to 1990 when a business major would get no starting salary at all. An absurd idea indeed.

equation is S = 20,250 + 1,050 * t
s is the average starting salary.
t is the number of years from 1990.
t = 0 references the year 1990.
t = 1, 1991, etc.
the S intercept is the value of S when t = 0.
that makes the S intercept 20,250.
the equation tells you what the average starting salary is for students majoring in business, by the number of years from 1990.
in 1990, the average starting salary is 20,250.
in 2000, the average starting salary is 20,250 + 1,050 * 10 * 1,050 = 30,750.
in 2020, the average starting salary is 20,250 + 1,050 * 30 = 51,750.
here's a graph that shows the average starting salary every 5 years from 1990 to 2000.
in the graph equation, y takes the place of S and x takes the place of t.
