Correct Question :----

• we have to Find the perpendicular distance between point (-7,-8) and y -axis.

Concept and formula used :----

• At y -axis we know that, value of x = 0 .

Solution :----

we have to Find the perpendicular distance between P(-7,-8) and y-axis...

we know that now the distance of any point from the y-axis is given by the x - coordinates ..

Here , in Question x - coordinate is given = (-7)

Hence , we can say that the perpendicular distance from p(-7,-8) is
