Review of Systems of Linear Equations

What are systems of linear equations?

• a set of two or more linear equations in the same variables
• a polynomial with three terms
• set of two or more linear inequalities in the same variables

If a system of equations has no solution, what does the graph look like?

• intersecting lines

• parallel lines

• perpendicular lines

• one line

What is the solution?

When you graph the exact same equation twice,

• you will have no solution. 
• you will have one solution.
• you will have infinite solutions. 
• you will graph a giraffe. 

How many solutions will this system have? 

• No solution
• One Solution
• I Don't Know
• Infinitely Many Solutions

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines

• no solutions

• Infinite solutions

• no solutions

• infinite solutions

• no solutions
