so in this example for being asked to graph X equals five. Well, I know it's one of our special cases. It's even a horizontal, a vertical line because I only have one variable here. So first we have to identify what type of line this will be. Well, because it's in the form X equals some constant that tells us that we're going toe, have a vertical line because that means the order. Each ordered pair should have five as its X value. So now how do we go about graphing this? Well, we know it's a vertical line, so now it's a matter of will where well, that's based off our constant value, which in this case is five. So because X is equal to five, we're gonna go along our X axis until we get to one. X is equal to five, and then we're going to draw a vertical line that goes through this point because all of the points on this line will have an X coordinate of five, which is exactly what our equation says. So again, to graph a vertical line, you first have to find the constant value on your X axis, which in this case was five and then you just draw a vertical line going through it Syracuse University
