Front

What defines a function in terms of x and y values?

Back

A relation is a function if each x-value corresponds to exactly one y-value.

Front

How can you determine the most likely outcome from a bar graph?

Back

To determine the most likely outcome, look at the height of the bar representing the category of interest and use that proportion to estimate the outcome.

Front

What is the first step in finding a term in a numerical pattern?

Back

Identify the pattern or rule that generates the sequence of numbers.

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

Back

Front

What does the term 'common difference' mean in an arithmetic sequence?

Back

The common difference is the constant amount that each term increases or decreases by in an arithmetic sequence.

Front

How do you graph a linear equation?

Back

To graph a linear equation, find two or more points that satisfy the equation and plot them on a coordinate plane, then connect the points with a straight line.

Front

What is the significance of the y-intercept in a linear equation?

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 a bar graph used for?

Back

A bar graph is used to represent categorical data with rectangular bars, where the length of each bar is proportional to the value it represents.
