Question:
The perpendicular distance of the point A(3, 4) from the y-axis is
(a) 3
(b) 4
(c) 5
(d) 7
Solution:
The perpendicular distance of a point from the y-axis is equal to the x-coordinate of the point.
∴ Perpendicular distance of the point A(3, 4) from the y-axis = x-coordinate of A(3, 4) = 3
Hence, the correct answer is option (a).
