Answer:
see the explanation
Stepbystep explanation:
The complete question in the attached figure
Let
x > the number of movies
y > the amount of money remaining on her gift card
we know that
The slope of the linear equation is equal to the unit rate
take two points from the graph
(0,18) and (2,12)
Find the slope
[tex]m=(1218)/(20)[/tex]
[tex]m=(6)/(2)=\$3\ per\ movie[/tex] > is negative because is a decreasing function
That means > Each movie she rents cost her $3, so her gift card balance will decrease $3 for every movie rented
The linear equation is equal to
[tex]y=3x+18[/tex]
For y=0
[tex]0=3x+18[/tex]
[tex]x=6[/tex]
so
6 is the maximum number of movies that Elyse can rent on line
