Find an equation of the vertical line through (-1/8, 3/2)

Answer 1

A vertical line through a point will always be equal to the x value of that point, so the equation of this line will be x=-1/8, this line will go through any point that has -1/8 as its x value.

Answer 2

Vertical lines have equations in the form x = h.

In this case, x = -1/8.
