Write the equation for the vertical line that contains the point E (-12,4).

The equation for a vertical line is x = a, where "a" is the x-coordinate of any point on the line.

In this case, the x-coordinate of point E is -12.

Therefore, the equation for the vertical line that contains the point E (-12,4) is x = -12.

To find the equation of a vertical line that passes through a given point, we need to remember that vertical lines have infinite slope. However, their equation can be represented as x = a, where 'a' is the x-coordinate of any point on the line.

In this case, the point E has coordinates (-12,4). Since the line is vertical, we know that the x-coordinate remains the same for all points on the line. Therefore, the equation of the vertical line passing through E is x = -12.

To write the equation for a vertical line, we need to determine the x-coordinate which remains constant for all points on that line. In this case, the point E is (-12,4), and we can see that the x-coordinate is -12.

A vertical line with a constant x-coordinate can be represented by the equation:

x = a

Where "a" is the constant x-coordinate. In our case, the equation for the vertical line that contains the point E can be written as:

x = -12
