a) (0, 30000) (1, 32000) (2, 34000) (3, 36000) , etc.
b) slope of the line is 2000 you take the first two points listed aove and you subtract the y values and divide by the subtraction of the x values
y1-y2/x1-x2
32000-30000/1-0
2000/1
c) y=2000x+30000
d) y=2000(5)+30000=40000
just plug 5 in for x

It appears that you are trying to reproduce a graph here and the line did not come through.

salary vector (9 points) vs. time-frame (4 years) is unclear. Are these 6-month intervals? If so extra period. If not, ???
