What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Front

What does the slope of a line represent?

Back

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

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect.

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 cause-and-effect relationship.

Front

What is correlation?

Back

Correlation measures the strength and direction of a linear relationship between two variables.

Front

What does a correlation coefficient of -0.26 indicate?

Back

A correlation coefficient of -0.26 indicates a weak negative correlation between the two variables.

Front

How do you find the slope of a line given two points?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What is the difference between association and causation?

Back

Association indicates a relationship between two variables, while causation indicates that one variable directly affects the other.

Front

What does it mean if a line has an undefined slope?

Back

An undefined slope means the line is vertical, indicating that the x-coordinates are the same for all points on the line.

Front

What is the graphical representation of an inequality?

Back

The graphical representation of an inequality shows a shaded region on one side of a boundary line, indicating all the solutions that satisfy the inequality.
