Point 1 of 5
30.3.1 Parallel and Coincident: Same Steepness
Core ideaTwo lines that tilt the same and never meet are parallel, with k₁=k₂ but different intercepts; match the intercepts too and they're the very same line.
Module goal. Study how lines relate to each other, judge their positions, find intersections, and compute distances, finishing the toolbox for lines.
