Question

Given below are some points, with their co-ordinates.
$P(4, 3), Q(-3, 2), R(5, 1), S(0, -4)$

What is the x-co-ordinate of point S ?

Answer 1

We know, any point in the $xy$ cartesian plane, is denoted by $(x-$coordinate$,y-$coordinate$)$
The point $S$ is given as $S(0,-4)$.
Hence, $x-$coordinate of point $S$ is $0$.
