Answer: The slope-intercept form is y = mx + b; m represents the slope, or grade, and b represents where the line intercepts the y-axis. If we are given the equation for the line of y = 2x + 1, the slope is m = 2 and the y-intercept is b = 1 or the point (0, 1), in that it crosses the y-axis at y = 1.
