Final answer:
The line passing through the point E(3,5) and with an undefined slope has an equation in the form x = 3.
Step-by-step explanation:
The equation of a line can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept. However, in this case, the slope is undefined, meaning the line is vertical.
Since the line passes through the point E(3,5), the x-coordinate will always be 3 and the equation will be in the form x = 3. Therefore, the correct answer is option a.
