The letter "m" represents the slope of a line, which is how steep the line is. The slope is often calculated from a graph as "rise / run" or from two points as m = (y2 - y1) / (x2 -x1) . The letter "b" represents the y-intercept value, which is the y value when the x coordinate is zero, or where the graphed line crosses the y-axis.
