A straight line drawn on a grid can be described by a rule connecting the x and y coordinates of every point on the line. This is known as the equation of the line. The equation of any straight line ...

Microsoft Excel is designed to organize and interpret small and large amounts of data. Building a curved graph in Excel based on X and Y data points is fairly simple. You begin by adding the data ...
