Question 204202
The following graph shows Bob’s salary from the year 2000 to the year 2003. He was hired in the year 2000; therefore, x = 0 represents the year 2000. 

2000=30,000 
2001=32,000
2002=34,000
2003=36,000 

a) List the coordinates of two points on the graph in (x, y) form.

(0, 2000) (3, 2003)

b) Find the slope of this line:  The slope is 1.

c) Find the equation of this line in slope-intercept form.

The equation is y = x + 1997

d) If Bob’s salary trend continued, what would his salary be in the year 2005?

We can use the linear function y = 2000x + 30,000 to find Bob's salary in 2005.

From 2005 to 2000, there are 5 years.  So, let x = 5.

y = 2000(5) + 30,000

y = 10,000 + 30, 000

y = $40,000
