Lets start by identifying slope. This is also known as change in y over change in x or rise over run. ERRATA Although I still wonder if the actual Y data are unrounded and different from what you presented there is no longer any difference in the Excel 2003 Line chart trendline formulas.
Y 3 2 x 2 y 2x-43.
M y y 1 x x 1. The slope of a line defines the steepness of the line and whether the line rises or falls. The equation of a line with slope -2 and y intercept 0 3 is written as follows. The slope of a line on the coordinate plane basically tells you how steep the line is.
