2024 Fall Final Exam Review II.

Front

What is a line segment parallel to the x-axis?

Back

A line segment parallel to the x-axis has the same y-coordinate for both endpoints, meaning it runs horizontally.

Front

What does an exponential function represent in a savings account model?

Back

An exponential function in a savings account model indicates that the balance grows at a constant percentage rate over time.

Front

What does the y-intercept of a linear graph represent in a loan payment scenario?

Back

The y-intercept represents the initial amount of the loan before any payments are made.

Front

What is the slope of a line?

Back

The slope of a line indicates the rate of change of y with respect to x, calculated as the rise over run.

Front

How do you write the equation of a line given the slope and y-intercept?

Back

The equation of a line can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line, defined by the equation y = mx + b.

Front

How can you determine if a function is linear from a table of values?

Back

A function is linear if the differences between y-values are constant for equal intervals of x.

Front

What does the term 'y-intercept' mean?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What is the significance of the starting amount in a savings account model?

Back

The starting amount is the initial deposit or balance before any interest or deposits are added.
