What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the equation of a line (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

Find the slope of the line: y = -5/4x + 3

Back

-5/4

Front

What does a zero slope indicate about a line?

Back

A zero slope indicates that the line is horizontal, meaning there is no change in y as x changes.

Front

What is an outlier in a data set?

Back

An outlier is a data point that is significantly different from other observations in a data set, often appearing far away from the cluster of points.

Front

What does it mean if a graph has no association?

Back

If a graph has no association, it means there is no discernible relationship between the variables being plotted.

Front

What is a positive correlation?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What is a negative correlation?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What is a scatter plot?

Back

A scatter plot is a graph that displays values for typically two variables for a set of data, showing how much one variable is affected by another.

Front

What does the term 'variable' mean in mathematics?

Back

A variable is a symbol used to represent an unknown value in mathematical expressions or equations.

Front

What is the purpose of a graph in data analysis?

Back

Graphs are used to visually represent data, making it easier to identify trends, patterns, and relationships.
