WebInterpreting results Using the formula Y = mX + b: The linear regression interpretation of the slope coefficient, m, is, "The estimated change in Y for a 1-unit increase of X." The interpretation of the intercept parameter, b, is, "The estimated value of Y when X equals 0." The first portion of results contains the best fit values of the slope and Y-intercept terms.

WebEquation for a Line. Think back to algebra and the equation for a line: y = mx + b. In the equation for a line, Y = the vertical value. M = slope (rise/run). X = the horizontal value. B = the value of Y when X = 0 (i.e., y-intercept). So, if the slope is 3, then as X increases by 1, Y increases by 1 X 3 = 3. Conversely, if the slope is -3, then ... WebIn This Topic.
