AB
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
2. Parallel lines have the same slope.
-2. Slopes of parallel lines are the same. If the lines are different it is the intercedpt that is different.
That one.
For any two perpendicular lines (save a vertical and a horizontal one), the product of their slopes is always -1. For two perpendicular lines with one having a slope of -2, the other will have a slope equal to -1 divided by -2, which equals 1/2.
Lines with no slope are horizontal lines or flat lines
Parallel
1/2
-2 (APEX)
Th opposite reciprocal. So if one line has a slope of 2 then the other line will have a slope of -1/2
Parallel lines have the same slope. So if you have a line with slope = 2, for example, and another line is parallel to the first line, it will also have slope = 2.
