Answer:
The equation is [tex]y=-4x+103[/tex]
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to
[tex]y=mx+b[/tex]
where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
[tex]m=-\$4\ per\ week[/tex] --> is negative because is a decreasing function
The y-intercept or initial value is
[tex]b=\$103[/tex]
substitute
[tex]y=-4x+103[/tex]
