This week, we have learned about slope. To find slope, we have the formula y(2)-y(1)/x(2)-x(1) from the coordinates of any 2 points on the line segment.

Other than just finding a slope, I also have learned how to define and find perpendicular line segments and parallel segments. For perpendicular segments, if two slopes multiple together, then we will get the answer -1. The slope of two-segment must be reversed in order to get the answer -1. for example one slope will be -2 and another slope will be 1/2( note that it must be one positive and one negative)

for two parallel slopes, their slope must be the same and they will never ever meet each other on the graph.
