Question

drag each label to the correct location on the graph. not all tiles will be used.

tony opens a savings account. the graph represents the amount of money in dollars that tony expects to deposit in his account in terms of the number of years since opening the account.

rate of change = dollars per year
initial value = dollars

y =

tiles:
2,500
7,500
5,000
2,500 + 5,000x
5,000 + 2,500x
5,000 + 7,500x

Explanation:

Identify the initial value

Using the Linear Functions knowledge point

$$ \text{Initial value} = y\text{-intercept} = 5,000 $$

Calculate the rate of change

Using the Rate of Change knowledge point

$$
LATEXBLOCK0
$$

Formulate the linear equation

Using the Linear Functions knowledge point

$$
LATEXBLOCK1
$$

Answer:

Drag each label to the correct location on the graph. Not all tiles will be used.

Tony opens a savings account. The graph represents the amount of money in dollars that Tony expects to deposit in his account in terms of the number of years since opening the account.

• \(y =\) <blank>\(5,000 + 2,500x\)</blank>
• rate of change = <blank>\(2,500\)</blank> dollars per year
• initial value = <blank>\(5,000\)</blank> dollars
