How many equations are generally needed to solve for two variables?

• Three

• Four

• One

• Two

Which method is NOT typically used to solve systems of linear equations?

• Elimination

• Substitution

• Graphing

• Integration

What is the first step in cleaning up a system of equations?

• Multiplying equations

• Dividing equations

• Adding variables

• Aligning variables and constants

What is the goal of the elimination method?

• To eliminate one variable

• To find the slope

• To add more variables

• To graph the equations

In the elimination method, what do you create to eliminate a variable?

• Random terms

• Identical terms

• Opposite terms

• Similar terms

What is the result of solving a system of equations using the elimination method?

• A single equation

• A graph

• An ordered pair

• A polynomial

What does the ordered pair represent in the context of solving linear equations?

• The intersection point of the lines

• The distance between the lines

• The midpoint of the lines

• The slope of the lines

Which of the following is a correct interpretation of the solution to a system of equations?

• The solution is the slope of the lines

• The solution is where the lines intersect

• The solution is the distance between the lines

• The solution is the midpoint of the lines
