WebSlope represents the steepness of the surface and is symbolized into three classes that are shown using color saturation (brightness). Aspect directions are represented by color, and the slope is represented by brightness. The slope values are in degrees, where the gray areas show slopes less than 5 degrees. Notes Web11 apr. 2024 · · a is the value when x is 0. b is termed as the slope and gives the change in y for a unit change in x. · If r=0.8 then r^2= (0.8)^2 = 0.64 which means x is explaining 64% variation in y.
