Question

How do you write an equation of a line with an undefined slope and passing through the point (-2,4)?

Answer 1

x = -2

Explanation:

Since the line has an undefined slope. This informs us that it is a vertical line parallel to the y-axis and passing through all points in the plane with the same x-coordinate.
Here the line passes through (-2 ,4). It will also pass through the points (-2 ,0),(-2 ,-4) and so on.

It's equation is written as x = - 2
