This video tutorial for Grade 8 Math covers solving special systems of equations algebraically using elimination. It explains the characteristics of special systems, including those with no solution or infinite solutions. The tutorial demonstrates how to use graphing and elimination methods to identify solutions, emphasizing the importance of recognizing parallel lines and identical equations. The video concludes with a preview of the next lesson on no solutions and infinite solutions.

• It introduces the concept of special systems.

• It contains unrelated content.

What are special systems of equations?

• Systems with no solution or infinite solutions.

• Systems that can only be solved graphically.

• Equations that are always inconsistent.

• Equations with no variables.

Which method is NOT used to solve systems of equations?

• Elimination

• Integration

• Substitution

• Graphing

What does it mean when two lines intersect?

• There is no solution.

• The lines are parallel.

• There are infinite solutions.

• There is one solution.

What happens when two lines are parallel?

• They intersect at one point.

• They never intersect.

• They have infinite solutions.

• They form a circle.

What is the result of multiplying the first equation by 2 in the elimination method?
