30.2.2 Slope: How Much You Climb for Each Step Right
Core ideaIt's the steepness of the climb: step 1 to the right and you rise k, where k=tanα=(y₂−y₁)/(x₂−x₁).
Module goal. Start from how steep a line is, master slope and the various forms of a line's equation, and learn to write down any line in the coordinate plane.
