Question

In a savings account scenario where a high school freshman starts with a balance of $1250 and after 35 weeks, the balance grows to $5372, what is the y-intercept of the linear equation modeling this situation? (Do not include units in your answer.)

a. 5372
b. 1250
c. 71.4
d. -1250

Answer 1

The y-intercept of the linear equation modeling the savings account scenario is the initial balance of $1250.

Step-by-step explanation:

In this savings account scenario, the linear equation modeling the situation would show the initial balance as the y-intercept since that is the value of the dependent variable (account balance) when the independent variable (time in weeks) is 0.

The y-intercept represents the starting balance of the savings account before any growth from interest or additional deposits is considered.

Given the options provided, the y-intercept is $1250, which is the initial amount the high school freshman starts with in their savings account.
