In this tutorial the author shows how to derive a slopeintercept equation of a line given an XY table. He explains that the general form of slope intercept form which is y = m*x + b. Now he intends to find value of slope, i.e. m first. Now slope is change in y over change in x. He computes the slope using the XY values from the table. Next he substitutes a pair of x, y value in the equation to compute the value of y intercept b. Now finally substituting the values in the equation the slopintercept form is obtained. This video is useful to learn how to derive a slopeintercept equation from a XY value table.
