Understanding Checking Account Graphs

The video tutorial explains how to sketch a graph for a linear function representing a student's checking account over time. It covers the concepts of the Y-intercept, rate of change, and constant. The tutorial guides viewers on plotting the graph, starting with an initial value of $200 and a weekly decrease of $20, and identifies the Y-intercept as the starting point on the graph.

What does the x-axis represent in the context of the student's checking account graph?

• The amount of money in the account

• The number of weeks

• The interest rate

• The number of transactions

How much money does the student start with in their checking account?

• $200

• $250

• $150

• $100

What is the y-intercept in the context of this graph?

• The total amount of money after 10 weeks

• The point where the graph crosses the x-axis

• The starting amount of money in the account

• The rate at which money is spent

Where does the graph touch the y-axis?

• At $100

• At $0

• At $300

• At $200

What does the $20 per week represent in the linear function?

• The rate of change

• The constant

• The total amount

• The y-intercept

How is the graph plotted using the given values?

• By marking every $100 increment

• By marking every $50 increment

• By marking every $20 increment

• By marking every $10 increment
