What is the mean of a set of numbers?

Back

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the count of numbers.

Front

How do you compare decimal numbers?

Back

To compare decimal numbers, align the decimal points and compare digit by digit from left to right.

Front

What does the slope of a line represent in an equation?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line represented by the equation y = mx + b?

Back

In the equation y = mx + b, m represents the slope of the line.

Front

How do you solve a linear equation for x?

Back

To solve a linear equation for x, isolate x on one side of the equation using inverse operations.

Front

What is the formula for calculating the mean of a data set?

Back

The formula for the mean is Mean = (Sum of all values) / (Number of values).

Front

How do you identify the slope from a graph?

Back

The slope can be identified by selecting two points on the line and using the rise over run method.
