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

• intersecting lines
• parallel lines
• the same line
• skew lines

Tags

TEKS.MATH.8.9A

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.
