WebIn mathematics, a projective plane is a geometric structure that extends the concept of a plane. In the ordinary Euclidean plane, two lines typically intersect in a single point, but there are some pairs of lines (namely, parallel lines) that do not intersect.

"WebThe denominator tells you the change in X -- how fast the X coordinate is changing (how fast the line is moving left/right). Horizontal lines do not go up/down. They just move left to right. This means the change in Y = 0, while the change in X = 1. 0/1 = 0 as a slope. Vertical lines go up/down, but they never go left or right. " - How many lines meet 4 lines in p3
