Respuesta :

calculista

Let

x--------> the number of months

y-------> represents the balance, in dollars, of a bank account

we know that

y=-50x+100

the rate of change is equal to the slope of the line

so

[tex]m=-50\frac{\$}{month}[/tex]

therefore

the answer is

the rate of change is [tex]-50\frac{\$}{month}[/tex]
