Why is the equation y = 4/x considered non-linear?

• Because it has a constant rate of change

• Because it can be written in slope-intercept form

• Because the variable is in the denominator

• Because it forms a straight line

What type of interest does Account A earn in the real-life application example?

• Simple interest

• Variable interest

• Compound interest

• No interest

Why is Account B considered non-linear in the real-life application example?

• Because it earns simple interest

• Because it starts at $100

• Because it is not a straight line

• Because it has a constant rate of change

What is the main difference between Account A and Account B in the real-life application example?

• Account A starts at $100, Account B starts at $200

• Account A is non-linear, Account B is linear

• Account A has a constant rate of change, Account B does not

• Account A earns compound interest, Account B earns simple interest
