Systems of Equations Review

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never intersect and have the same slope.

Front

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

Back

It means that the equations represent the same line, and every point on that line is a solution.

Front

Solve the system: 2x + 3y = 6 and 4x + 6y = 12.

Back

Infinitely Many Solutions

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other.

Front

Solve: 3x + 2y = 12 and 3x + 2y = 18.

Back

No Solution

Front

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

Back

It means that the lines represented by the equations are parallel and will never intersect.

Front

Solve: 5x + 3y = 7 and y = 4.

Back

(-1, 4)

Front

What is the substitution method in solving systems of equations?

Back

The substitution method involves solving one equation for one variable and substituting that expression into the other equation.

Front

Solve the system using elimination: 2x + 3y = 6 and 4x + 6y = 12.

Infinitely Many Solutions

Front

What is the graphical representation of a system of equations?

Back

It is the intersection point(s) of the lines represented by the equations on a coordinate plane.
