Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is.

What is the y-intercept of a linear equation?

Back

Front

How do you determine if a point is a solution to a linear equation?

Back

To determine if a point (x, y) is a solution, substitute the x-value into the equation and see if the resulting y-value equals the y-value of the point.

Front

What is a linear inequality?

Back

A linear inequality is similar to a linear equation but uses inequality signs (>, <, ≥, ≤) instead of an equal sign. It represents a region of solutions on a graph.

Front

How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding linear equation as a dashed or solid line, then shade the region that satisfies the inequality.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as a set of ordered pairs, a graph, or an equation.

Front

What does f(4) represent in a function?

Back

f(4) represents the output of the function when the input is 4. It is the value of the function at that specific point.

Front

What is causation in statistics?

Back

Causation indicates that one event is the result of the occurrence of another event. It implies a direct relationship between two variables.

Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together. It does not imply causation.
