The problem shows Tara starting with $80 in her bank account and withdrawing $15 each week, which reduces her balance. The table lists the number of weeks $x$ and the corresponding account balance $y$.

To form the equation, we can observe that:

• The starting balance at $x = 0$ is $80.
• Tara withdraws $15 every week, which means her balance decreases by $15 for each additional week.

The equation for this scenario can be written as: $y = 80 - 15x$

Now, for the equation in the blank format: The left side will be $y$, and the right side will be $80 - 15x$, so: $y = 80 - 15x$

Does this clarify things for you? Let me know if you'd like further details!

Here are 5 related questions to consider:

1. What would the equation be if Tara withdrew $20 each week instead of $15?
2. How many weeks will it take for Tara's account to reach $0?
3. What is the rate of change in her account balance per week?
4. Can you express the number of weeks $x$ as a function of the account balance $y$?
5. How would the equation change if Tara started with $100 instead of $80?

Tip: To find the equation of a line from a table, look for the initial value and the rate of change (slope).
