Question

What is the distance from(-2,-6) to the vertical axis

Answer 1

The vertical axis is the y-axis. To find the distance from a point to y-axis (coordinate x=0) you use the coordinate x in the point (x,y) in the next formula:

$d=\lvert x\rvert$

As the diatance is a positive quantity you get the distance from a absolute value.

For the given point:

Coordinate x = -2

$d=\lvert-2\rvert=2$

Then, the distance from (-2, -6) to the vertical axis is 2 units
