if x is the number of years since 2000 and y is the percent of people using travel services, the following equations represent the percent of people using travel agents and the percent of people using the internet to plan travel. travel agents: y=-2x+30 internet: y=6x+41

If X Is The Number Of Years Since 2000 And Y Is The Percent Of People Using Travel Services The Following Equations Represent The Percent Of People Using Travel class=

Answer :

First we have to plot two points per graph

Function 1

y=-2x+30

Points

x y

0 -2*0 + 30 = 30

10 -2*10 + 30 = 10

Points: (0,30) and (10,10)

Function 2

y=6x+41

Points: (0,41) and (1,47)

x y

0 6*0 + 41 = 41

1 6*1 + 41 = 47

Then we plot the graph

From the graph we can deduce that the year when travel agents and Internet were used equally was approximately 1999 ( one year before 2000)
