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 on a graph.

Front

How do you find the solution to a system of equations graphically?

Back

To find the solution graphically, plot each equation on the same graph and identify the point(s) where the lines intersect.

Front

What does a positive correlation indicate?

Back

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

Front

What does a negative correlation indicate?

Back

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

Front

What is the correlation coefficient (r)?

Back

The correlation coefficient (r) is a statistical measure that describes the strength and direction of a relationship between two variables, ranging from -1 to 1.

Front

What does an r value of approximately 0.85 indicate?

Back

An r value of approximately 0.85 indicates a strong positive correlation between the two variables.

Front

What does an r value of approximately -0.82 indicate?

Back

An r value of approximately -0.82 indicates a strong negative correlation between the two variables.

Front

What is the solution to the system of equations y = x - 6 and y = -3x + 2?

Back

The solution is (2, -4).

Front

What is the significance of the intersection point in a system of equations?

Back

The intersection point represents the solution to the system, where all equations are satisfied simultaneously.

Front

What is a weak correlation?

Back

A weak correlation indicates a slight relationship between two variables, often represented by an r value close to 0.
