      20. To solve for the value of absolute zero, use the slope and y-intercept of the regression line to set up the equation, y= ax+b. Absolute zero is the temperature where the volume of the gas equals zero. This is the . x-intercept of the line. To calculate this value, set . y=0. and solve for . x. GAY- LUSSAC’S LAW

      between an observed observation and a predicted or fit value. Graphically, it is the vertical distance between a point and the line of best fit. It is found by subtracting the fitted -value from the observed y-value: An . outlier, in the regression sense, is a value with a large, in absolute value, residual.
