How many solutions does this system of equations have?

• one solution

• infinitely many solutions

• no solution

• two solutions

Parallel Lines never intersect because...

• they have the same slopes. 

• they have different slopes.

• they have the same y-intercept.

• they have different y-intercepts. 

The solution is:

• no solution

• infinitely many solutions

What is the first step in solving a system by graphing?

• Get x by itself

• Compare the slopes of both equations

• Write both linear equations in slope-intercept form

• Write both equations in standard form

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

The solution to a system of equations is any ordered pair that makes both equations true. 

• True
• False

If m=3 and b=6, what is the correct slope intercept equation?
