2001=32,000
2002=34,000
2003=36,000
a) List the coordinates of two points on the graph in (x, y) form.
(___, __),(___, ___)
b) Find the slope of this line:
c) Find the equation of this line in slope-intercept form.
d) If Bob’s salary trend continued, what would his salary be in the year 2005?

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
