Question

What is the equation of a vertical line passing through the point (−5, −1)? y = −5 y = −1 x = −5 x = −1

Answer 1

The equation of any vertical line is
`x=`

So if we want it to pass through (-5,-1), the y value doesn't matter because our line is vertical, it will hit every y value. So we look at the x value. In this case, it's -5. So if we want it to go through
`x=-5`, the equation will be
`x=-5`!

Answer 2

The correct option is 3.

Explanation:

It is given that a vertical line passing through the point (−5, −1).

If a vertical line passes through a point (a,b), then the equation of vertical is

`x=a` .... (1)

In the given point the value of a is -5 and the value of b is -1.

Substitute a=-5 in equation (1), to find the equation of vertical line.

`x=-5`

The equation of a vertical line is x=-5 which passing through the point (−5, −1).

Therefore the correct option is 3.
