Zara made an initial deposit to a bank account and then added a fixed amount every week. The table shows the money in her account. Which equation represents the situation? Hint: Plug in the values for x (1, 2, 3, 4, 5) into each equation below until you get the value for y.

• y = 30x + 100

• y = 20x + 120

• y = 120x + 120

• y = 50x + 100

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
