Question

The distance of the point (-8,-7) from y axis is
​

Answer 1

Answer:

Distance from y axis is 8 units

Answer 2

Given:

A point P(-8,-7) in a 2-D coordinate system.

To Find:

The distance of the point(-8,-7) from the y-axis.

Solution:

The Solution can be determined by using the concepts of 2-D coordinate geometry.

1. P(-8,-7) is the given point.

Let P(x,y) be two points in the coordinate system, x is defined as the point which is at a distance of x units from the y-axis, y is defined as the point which is at a distance of y units from the x-axis.

2. Since distance can never be negative, the distance is taken as Positive irrespective of the sign of the values of the point. ( Example: distance of P(-1,2) from y-axis is considered as 1 unit, but not -1 because distance can never be negative).

3. Considering the definition and the given example, we can now get the answer.

=>P(-8,-7) ( where -8 belongs to the x-axis, and -7 belongs to the  y-axis.)

The distance is asked from the y-axis, So x units will be the answer. (ignore the negative signs)

Therefore, the distance of the point (-8,-7) from the y-axis is 8 units.
