Question

What is the equation of the line?​

Answer 1

The equation of the line is x = 3.

Explanation:

When a line is parallel to the y-axis, its gradient will be undefined. There is no y-intercept and the line touches x-axis so the equation is x = 3.

Answer 2

The line cuts the X axis at
`x=3` and is parallel to the Y axis.

Thus the equation of the line is $\boxed{x=3}$
