Work Step by Step

Two points clearly on the line are (3,0) and (3,1). By going from one point to the other, we see that we move up 1 units and to the right 0 unit, giving us a rise/run slope that's undefined. Since the line crosses the x-axis at (3,0), the x intercept is b=3. Therefore, our line is: x=3.
