Let

y ------> the year

x ----> revenue

so

Plot the given ordered pairs

see the attached figure

(please wait a minute to plot the points)

In the graph the x-coordinate 0 represent year 1990

Find out the equation of the line

take two points

(1990, 5.7) and (2006, 11.5)

Find the slope m

m=(11.5-5.7)/(2006-1990)

m=5.8/16

m=0.3625

Find the equation of the line in slope intercept form

y=mx+b

we have

m=0.3625

point (1990, 5.7)

substitute and solve for b

5.7=(0.3625)(1990)+b

b=-715.675

therefore

y=0.3625x-715.675
