What is the equation for the line parrallel to y-axis and passing (2, -4)?

Expert Solution
Step 1

Equation of a line parallel to y-axis will be a vertical line and is of the form:

x = k

where, k is x value of the coordinate through which line passes.

We are given the line passes through (2, -4)

Hence, k = 2 in our case

Equation of line parallel to y-axis and passing through (2, -4) is given by:

x = 2 or x - 2 = 0
