Today we were discussing about parallel and perpendicular lines.Mathematics often deal with parallel and perpendicular lines. Since these are such popular lines, it is important that we remember some information about their slopes.
Parallel Lines:
-->have the same slope
l1 // l 2 --> m1 = m2
* Remember that parallel lines never intersect.
Here is an example of a graphed parallel lines:
Parallel Lines:
-->have the same slope
l1 // l 2 --> m1 = m2
* Remember that parallel lines never intersect.
Here is an example of a graphed parallel lines:
y=-2x +3
3
y=-2x -1 These lines are all parallel. They all have the same slope (m).
3
y=-2x+o (Remember y = mx + b)
3
Perpendicular Lines:
-->have negative reciprocal slopes.
*Remember that the perpendicular lines meet to form right angles.
Here is an example of a graped perpendicular lines:
I hope this all make sense ....becuase I did my best ...!! Gudluck to the next blogger........haha!!
The next bLogger is TAN!!
