pair of linear equation in two variable

What is pair of linear equations in two variables?

• a set of two or more linear equations in the same two variables

• a polynomial with three terms

• set of two linear equations in same two variables

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

• intersecting lines
• parallel lines
• skew lines
• intersecting lines

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

• Parallel lines
• the same line 
• Intersecting lines

How can you tell if a point is a solution to a system?

• It makes the first equation true.
• The (x,y) coordinates satisfy both equations
• It makes logical sense
• It makes neither equation negative

If a pair of linear equations is consistent, then the lines will be 

•  parallel
• always coincident
• intersecting or coincident
•  always intersecting

What is the solution to a system of equations?

• The point that the equations have in common.

• The point where the two lines intersect.

• All of the above.

^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)

• no solution

If a pair of linear equations is consistent, then the lines will be 

•  parallel
