REASSESSMENT WORK Systems of Equations Test review (L13 & L14)

Front

What is a system of equations?

Back

A set of two or more equations with the same variables that are solved together.

Front

What does it mean to solve a system of equations?

Back

Finding the values of the variables that satisfy all equations in the system simultaneously.

Front

What is the graphical representation of a system of equations?

Back

The point(s) where the graphs of the equations intersect.

Front

What is the substitution method in solving systems of equations?

Back

A method where one equation is solved for one variable, and that expression is substituted into the other equation.

Front

What is the elimination method in solving systems of equations?

Back

A method where equations are added or subtracted to eliminate one variable, making it easier to solve for the other.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point in a coordinate plane.

Front

What does it mean if two lines are parallel in a system of equations?

Back

The system has no solution because the lines never intersect.

Front

What does it mean if two lines are coincident in a system of equations?

Back

The system has infinitely many solutions because the lines lie on top of each other.

Front

How do you determine the solution of a system of equations graphically?

Back

By finding the intersection point of the lines representing the equations.

Front

What is the first step in solving the system: 3x + 3y = 27 and 3x - 3y = 3?

Back

You can simplify both equations by dividing them by 3.
