Question

Write the distance of point $p(2,-1)$ from the $y$- axis.

Answer 1

We know that, distance of the point from $y$ - axis is given by the abscissa of the point point ie $x$ - coordinate.

Therefore, Distance of point $p(2,-1)$ from the $y$ - axis will be $2$ units as $2$ is the abscissa of the point.
