Answer:
The slope is [tex]-\frac{350}{month}\[/tex]
Step-by-step explanation:
This saving account is declining a fixed amount every month, this means that the function that represents this decline is linear.
The other thing we know is that originally (september 1), the account has a balance of $4900, and this is the intercept.
Therefore, for a linear function depending of the variable "x", we can write that
[tex]f(x)= (-\frac{350}{month}x+4900)\[/tex]
where the units were factored. Then the slope is
[tex]-\frac{350}{month}\[/tex]
