A line with an undefined slope is a vertical line. Vertical lines have equations of the form \( x = a \), where \( a \) is a constant.
Since the line passes through the point (5, 5), the equation of the line is:
\[ x = 5 \]
This means that for all points on this line, the x-coordinate will always be 5, while the y-coordinate can take any value.
