Lesson 26 Student Outcomes
• Students know that when a system of linear equations has no solution, i.e., no point of intersection of the lines, then the lines are parallel.
Lesson 26 Student Summary
By definition, parallel lines do not intersect; therefore, a system of linear equations that graph as parallel lines will have no solution.
Parallel lines have the same slope, but no common point. Verify that lines are parallel by comparing their slopes and their y-intercepts.
Lesson 26 Opening Exercise
(1) Two distinct, non-vertical lines in the plane are parallel if they have the same slope.
(2) If two distinct, non-vertical lines have the same slope, then they are parallel.
