Correct option (a) 9
Solution:
We know that the x-coordinate for the y-axis is zero.
A(x,y) is perpendicular distance from the y-axis at its x-coordinate.
At point p(-9,-8), the x-coordinate is 9.
Hence, the perpendicular distance from the y-axis of point p(-9,-8) is 9 units.
Therefore, the distance is 9 units.
