Unit 3: Linear Functions Test Review

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line. It can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a positive relationship in a scatterplot indicate?

Back

A positive relationship in a scatterplot indicates that as one variable increases, the other variable also increases.

Front

How do you find the common difference in an arithmetic sequence?

Back

The common difference is found by subtracting any term from the subsequent term in the sequence.

Front

What is the formula to find the nth term of an arithmetic sequence?

Back

The nth term (a_n) can be found using the formula: a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

Front

What is the common difference in the sequence: -34, -29, -24, -19?

Back

The common difference is d = 5.

Front

How do you determine the next terms in an arithmetic sequence?

Back

To find the next terms, add the common difference to the last known term.

Front

What is the 35th term in the arithmetic sequence: -10, -14, -18, -22?

Back

The 35th term is -146.

Front

What does a negative relationship in a scatterplot indicate?

Back

A negative relationship indicates that as one variable increases, the other variable decreases.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

What is an arithmetic sequence?

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.
