It passes through(-1,4) and is perpendicular to the y-axis

The parallel line would be x = -1

Step-by-step explanation:

If a line is parallel to the y axis, then it is a vertical line. All vertical lines can be written in the form of x = (a number). That number can be found as the x-coordinate in the ordered pair given.

x = -1

the two may have that, even a breakdown is probably offered
