Slopes and Equations of Lines

Which statement correctly describes the graph?

• The lines are parallel because they have different slopes.

• The lines are NOT parallel because they have different y-intercepts.

• The lines are parallel since they have the same slope and different y-intercepts.

• The lines are perpendicular.

Given the equations below determine if they are parallel or not.  y = 4x - 2 and  y = 5 + 4x

• Yes, They are parallel

• No, They are not parallel
