Compare this to the slope-intercept form of a linear equation:
y = m*x + b, where m is the slope and b is the y-intercept.
Does this help you determine the y-intercept for the graph of a direct variation equation?
If you're still confused, remember that any point on the y-axis has an x-coordinate of 0. So you can find the y-intercept by substituting 0 for x...........
