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

• Parallel lines - same slope, different y-intercept

• The same line - same slope, same y-intercept

• Intersecting lines - different slope (y-intercept can be the same)

• Infinite Solutions same slope, same y-intercept

• No solution parallel lines: same slope, different y-intercept

• One solution

  intersecting lines: different slopes

• Hint: did you solve the bottom equation for y to put into slope-intercept form?
