What is a linear relationship in a scatter plot?

Back

A linear relationship in a scatter plot indicates that as one variable increases or decreases, the other variable does so in a consistent manner, forming a straight line.

Front

What does the correlation coefficient 'r' represent?

Back

The correlation coefficient 'r' quantifies the strength and direction of a linear relationship between two variables, ranging from -1 to 1.

Front

What does a correlation coefficient of -1 indicate?

Back

A correlation coefficient of -1 indicates a perfect negative linear relationship between two variables.

Front

What does a correlation coefficient of 1 indicate?

Back

A correlation coefficient of 1 indicates a perfect positive linear relationship between two variables.

Front

What does a correlation coefficient of 0 indicate?

Back

A correlation coefficient of 0 indicates no linear relationship between the two variables.

Front

How do you determine if a point is a solution to a system of equations?

Back

A point is a solution to a system of equations if it satisfies all equations in the system when substituted into them.

Front

What is an ordered pair in the context of coordinate geometry?

Back

An ordered pair is a pair of numbers (x, y) that represent a point on a Cartesian coordinate system, where 'x' is the horizontal position and 'y' is the vertical position.

Front

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable in a linear equation.

Front

What is 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 the dependent variable when the independent variable is zero.
