Answer:

[tex]y=-5x+25[/tex]

The graph in the attached figure

Step-by-step explanation:

Let

x ----> the number of days

y ----> the amount of money in  her bank account

we know that

The equation of the line in slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope or rate

b is the y-intercept or initial value

In this problem we have

The slope is equal to

[tex]m=-5\ \$/day[/tex] ----> is negative because is a decreasing function

[tex]b=\$25[/tex] ----> initial amount in the account bank

substitute

[tex]y=-5x+25[/tex]

see the attached figure to better understand the problem
