Example 1
Can two lines that intersect be parallel to each other?
Example 2
Can two lines that lie on the same plane be parallel to each other?
Example 3
Line u is parallel to line l and line l is parallel to line i. Is it true that line u is parallel to line i?
Example 4
Line j is parallel to line k. If line j has the equation y = 3x – 1, what slope must line k have?
Example 5
Line p is parallel to line q. If line p has the equation 4x + 5y = 15 and line q passes through point (5, 5), what is the equation of line q?
