A graph of x=3 would simply be a vertical line through x=3. Because there is no y value or y intercept, we assume the slope in undefined, therefore, the line goes strictly vertically through x=3.

Just for future reference, if you were to have an equation with y=, let’s say y=4, the slope would be zero, and the graph would be a straight line horizontally through y=4 (4 on the y axis).
