Question

vanessa opens a new savings account. she makes an initial deposit, and then deposits the same amount each week. the total number of dollars in the account, y, is a function of the number of weeks, x. initial value: 10. is the rate of change positive or negative? positive. how can you find the rate of change? rate of change = (change in y - values)/(change in x - values) = (15 - □)/(1 -?). number of weeks, x | amount saved, y 0 | 10 1 | 15 2 | 20 3 | 25

Explanation:

Step1: Identify the formula for rate of change

rate of change = $\frac{\text{change in }y\text{-values}}{\text{change in }x\text{-values}}$

Step2: Find the values for the formula

When calculating the rate of change using the points $(x_1,y_1)=(0,10)$ and $(x_2,y_2)=(1,15)$:
The change in $y$-values is $15 - 10$ (since $y_2 = 15$ and $y_1=10$)
The change in $x$-values is $1 - 0$ (since $x_2 = 1$ and $x_1 = 0$)

Answer:

The first box is filled with $10$ and the second box is filled with $0$.
