Which statement is true about the graphs of the two lines y = -x + 2 and y=-x-? O The lines are perpendicular to each other because and are opposite reciprocals of each other.
O The lines are perpendicular to each other because 2 and – are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and -- are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 1 are not opposite reciprocals of
each other.

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 ∠leo ≅ ∠neo transitive property of equality 4 m∠leo = 90° definition of a perpendicular bisector 5 m∠neo = 90° definition of a perpendicular bisector 6 le ≅ en definition of a perpendicular bisector 7 δole ≅ δone side-angle-side (sas) postulate 8 ol ≅ on cpctc nina made two errors in the proof. identify and correct the errors.
