Hola chicos, it's Olaf. Hope everyone's long weekend has been going great. To recap on a few days ago, Rainbow Week was such a success! It was great to see everyone coming together in solidarity with the LGBT + community plus the treats were really good. Okay but before I get carried away, a quick shout out to our last scribe, because now we know how to graph lines by their slope and point and we learned the formula to find slope. (Rise over Run.) Here is just an easy peasy review of Perpendicular and Parallel lines and their slopes. 1) Parallel Starting off, parallel lines are two lines of a plane that never meet but are the same distance apart. Example: Slopes of Parallel lines have the same basis. They always have the same slope and don't intersect. These lines continue forever (∞) without touching. Slope is a measure of the angle of a line from the horizontal. We know parallel lines must have the same angle, therefore they have the same slope. This graph demonstrates this effect: As we can see, because both lines have a slope of 3/4 and are the same distance apart, it's safe to say it's defiantly an example of a Parallel line slope. 2) Perpendicular So what are perpendicular lines? Well to make it easy, perpendicular lines are lines that meet at right angles which are 90 degrees. It's quick to spot a difference from parallel lines because it intersects. Perpendicular lines have slopes that are negative reciprocals. An example could be: A slope: m = - 4/5 Which if it's changed to perpendicular would be: m(┴)= 5/4 Ex: a/b = -b/a Note: ┴ just represents perpendicular. * Happy Victoria Day! *
