Question

Points A and B have the same x-coordinates but opposite y-coordinates.

How many units away are each of the points from the y-axis?
3
4
6
7

Answer 1

they are 4 unit away from the Y axis because you are counting the square units from Y not the lines across.

Answer 2

4 units

Explanation:

Let's find the answer.

There is always two coordinates in each point, so a point coordinates is for example (a,b).

Using a 'XY' coordinates, coordinate 'a' and '-a' means within the X-axis 'a' units away (right direction) and '-a' units away (left direction) from the Y-axis. In the same way coordinate 'b' and '-b' means within the Y-axis 'b' units away (upward direction) and '-b' (downward direction) from the X-axis.

Because your points A and B have the following coordinates:

A=(-4,3) and B=(-4,-3) then both of them are -4 units away from Y-axis, or, which is the same, 4 units away from the Y-axis in a left direction.
