(402.5- 285.7) / (1995 - 1990)

anonymous · Answer

it says that the expenditure increases every year...or the rate of increase of expenditure is positive

anonymous · Answer

so i divide them both after subtracting?

anonymous · Answer

it is important to denote that such slope is given in billions per year.

anonymous · Answer

yes that gives the slope....change in dependent quantity upon change in independent quantity

anonymous · Answer

i got 116.8 divided by 5..is that right?

anonymous · Answer

i got 23.36

anonymous · Answer

yeah..as long as ur subtracting right

anonymous · Answer

so what does the slope tell me?

anonymous · Answer

the division was right, both 116.8/5 and 23.36 billions per year

anonymous · Answer

so the slop of the line is 116.6 over 5?? im confused

anonymous · Answer

understood?

anonymous · Answer

i kind of understand, still a bit confused!

anonymous · Answer

here is the method: y1-y0/x1-x0, considering years on the x axis and billions on the y axis. Being also x1,y1 the las point and x0,y0 the first point you will use to draw a line of which the slope is to be calculated.
