The document describes graphing a line using the equation y = mx + b, where m is the slope and b is the y-intercept. It provides an example of the line y = 2x + 3, with a slope of m = 2 and a y-intercept of b = 3. A table and graph are included to show the line passing through the points (0,3) and (1,5).
