Question

Amy began with $25 in her bank account and spend

Answer 1

Answer:

$y=-5x+25$

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

$y=mx+b$

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

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

$b=\ 25$ ----> initial amount in the account bank

substitute

$y=-5x+25$
