What is the equation of the line that passes through the point $(-7,4)$ and has an undefined slope? Answer Attempt 2 out of 2

Step 1 ：The equation of a line with an undefined slope is a vertical line. The equation of a vertical line is of the form x = a, where a is the x-coordinate of any point on the line.

Step 2 ：Given that the line passes through the point (-7,4), the equation of the line is \(x = -7\).

Step 3 ：So, the final answer is \(\boxed{x = -7}\).
