Review Systems of Equations

What is the solution to the system?

• (-1, 3)
• (3, -1)
• (3, 1)
• (1, 3)

^{What is the solution?} 

• (1, 1)
• (-1, 1)
• (-1, -1)
• (1, -1)

Parallel Lines never intersect because...

• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts.
