Once you get the equation of a line, you must take a few steps to actually graph it. Let's say that the equation is y=1/2+2. First you plot the "b" on the y-axis, which in this case is 2. You would then follow the slope, which is 1/2. You would go, from 2, up one coordinate, to the right 2, and continue this until you have about three to four points if possible. Then, from 2 on the y-axis, go down 1, and left 2. Continue this until you have about three to four points in that direction. Then take your ruler and connect the coordinates together. This is your line! Another example: If you have y=1/4x+9, you would plot a point on the 9 of the y-axis. Then go up one, and right four until about three points. Then go down one and left four until three points. Connect the dots and you're finished! Now what if it was y=-1/3-4? You would plot the negative four just like a positive, but now you would go down one and right four. Yes! It's that simple! That's how you graph a line's equation.
