Graphing lines with integer slopes Let's graph y = 2x + 3. Recall that in the general slope-intercept equation y =mx+b, the slope is given by m and the y-intercept is given by b. Therefore, the slope of y = 2x + 3 is 2 and the y-intercept is (0, 3). In order to graph a line, we need two points on that line. We already know that (0, 3) is on the line. Additionally, because the slope of the line is 2, we know that the point (0+1, 3+2) = (1,5) is also on the line.
