Coordinate$\left(x,y\right)$ of a point is an ordered pair of numbers; that is, a number on the x-axis called an x -coordinate, and a number on the y-axis called a y -coordinate.

In rectangular coordinate system any point be in the form of $\left(x,y\right)$.

• In Quadrant I, both the coordinates of ordered pair are positive, that is, $\left(+,+\right)$.
• In Quadrant II, first number is negative and second is positive, that is, $\left(−,+\right)$.
• In Quadrant III, both the coordinates of ordered pair are negative, that is, $\left(−,−\right)$.
• In Quadrant IV, first point is positive and second is negative, that is, width="42">+,−.

In order to plot the point $\left(3,0\right)$, observe that $\left(3,0\right)$ lies on x-axis.

Steps to plot the coordinates $\left(3,0\right)$are:

• Move to positive x-axis by 3 units starting from origin as value of x is 3.
• Then do not move on y-axis direction as value ofy is 0.

The plot of the coordinate as shown below:
