8R Unit 4 Test

Front

What is a solution of a system of equations?

Back

An ordered pair (x,y) that satisfies all equations in the system.

Front

How do you find the solution using substitution?

Back

Substitute one equation into another to find the values of x and y.

Front

What does it mean if a system of equations has no solution?

Back

The lines representing the equations are parallel and do not intersect.

Front

What does it mean if a system of equations has infinite solutions?

Back

The equations represent the same line, so every point on the line is a solution.

Front

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

Back

The point where the graphs of the equations meet, representing the solution.

Front

If the solution to a system is (2,1), what does this represent?

Back

It represents the values of x and y that satisfy both equations in the system.

Front

What is the first step in solving a system of equations by substitution?

Back

Solve one of the equations for one variable in terms of the other.

Front

What is the graphical representation of a system of equations?

Back

It is the intersection of the lines representing each equation.

Front

What is the significance of the ordered pair (-1, -2) in a system of equations?

Back

It is the solution that satisfies both equations in the system.

Front

What does it mean if a system of equations has a unique solution?

Back

The lines intersect at exactly one point, indicating one solution.
