WebSep 4, 2015 · This tallies with the algebraic fact that the correlation between estimated slope and intercept tends to zero as MSD(x) → ± ∞ and, when ˉx ≠ 0, towards ± 1 (the sign is the opposite of the sign of ˉx) as MSD(x) → 0. Correlation of slope and intercept estimators was a function of both ˉx and the MSD (or RMSD) of x, so how do their ... WebThe greater the magnitude of the slope, the steeper the line and the greater the rate of change. By examining the equation of a line, you quickly can discern its slope and y-intercept (where the line crosses the y-axis). The slope is positive 5. When x increases by 1, y increases by 5. The y-intercept is 2. The slope is negative 0.4. boost bootstrap options
