The following graph shows Bob’s salary from the year 2002 to the year 2005. He was hired in the year 2002; therefore t = 0 represents the year 2002.

These are the points on the graph!

O year = $41000
1 year = $43000
2 year = $46000
3 year = $48500

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

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

If Bob’s salary trend continued, what would his salary be in the year 2008?

  1. Well, we calculated the slope in another of your posts. It was 2500.

    That means each year his salary increases by $2500. It shouldn't be too hard to figure out what it is in 2008 with that information.
