Question

The distance of the P (4, 3) from the X –axis is (A) 2 units (B) 3 units (C) 4units (D) 5 units

Answer 1

Answer:

(B) 3 units

Step-by-step explanation:

First thing that should be clear in your mind is that whenever they will ask the distance from X-axis, Y-axis, it always means the perpendicular distance.

Next, when you will plot the point P (4,3) on graph, you will take 4 units from X-axis and 3 units from Y-axis. If you notice from the graph, the distance of point  P(3,4) from X-axis will be 3 units (y-coordinate) and the distance of point P(3,4) from Y-axis will be 4 units(x-coordinate).Hence in this way you can easily make out the distance from X-axis or Y-axis.

Answer 2

Answer:

By definition, for any point (x,y), the distance of the point from Y-axis is |x| and from X-axis is |y|. So, the distance of (4,-3) from X-axis is |-3| = 3 units.
