graph the equation x = 3
.
On the x-axis go to the point where x is +3. Put a dot at that point. Next take a straight
edge and use it to make a vertical line through that point. That vertical line is the graph.
Note that it is parallel to the y-axis, but is 3 units to the right of the y-axis.
.
Think of it this way ... y can be any value but the corresponding value of x is always 3.
You can pick any point on the graph, and the value of x is always 3 for that point. As
examples (3, -8), (3, 10), and (3, 0) are all points on the graph.
.
Hope this helps you to understand the meaning of an equation x = k where k is a constant.
The graph will always be a vertical line through the point k on the x-axis.
