As the differences between the data points and the line grow, the r-squared value drops, with 0.000 being the lowest possible value. Why do we always take change in y over change in x Why not vice versa ? The slope correction is always negative as horizontal distance will be shorter than the measured slope distance. This formula is what you would use to calculate the concentration of that solution or what input is needed to launch the marble a certain distance. Use the equation h = (x 2 + y 2 ) slope distance =.
