The equation of a vertical line that passes through the point is given by;
The given point is .
This implies that,
is therefore the equation of the vertical line that passes through .
The correct option is 3.
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
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.
The equation of a vertical line is x=-5 which passing through the point (−5, −1).
Therefore the correct option is 3.
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 , the equation will be !
