Question

Write the equation of the line, which is parallel to $y-axis$ and passing through $(3,5)$.

Answer 1

Finding the equation of line:

The equation of line parallel to $y-axis$ is written in the form $x=a.$

where $a$is the $x$ coordinate.

here $a=3$

i.e. $x=3$

Thus, the Equation of line parallel to $y-axis$ is $x=3$ OR $x-3=0$.
