Video Lesson on PARALLEL Slope and Lines
PARALLEL lines have EQUAL SLOPES. So if one line has a slope of 2/3, then a parallel line has a slope of 2/3.
Video Lesson on PERPENDICULAR Slopes and Lines
PERPENDICULAR LINES have slopes that are NOT EQUAL. They are OPPOSITE IN SIGN (if one is negative the other is positive; if one is positive the other is negative) AND they are FLIPPED (reciprocals). So if one line has a slope of 2/3 then a perpendicular line has a slope of - 3/2
