Question

Graph each ordered pair on a coordinate grid.

$\left(2,-1\right)$

Short answer

The ordered pair on a coordinate grid is as shown below:

Step-by-step solution

Step 1. State the concept for finding the coordinates of a point.

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, $\left(+,-\right)$.

Step 2. State the steps to plot the coordinates.

In order to plot the point $\left(2,-1\right)$, observe that$\left(2,-1\right)$is in fourth Quadrant.

Steps to plot the coordinates$\left(2,-1\right)$are:

• Move to positive x axis by 2 unitsstarting from originas value ofx is 2.
• Then move in negative y direction by 1 unit as value of y is $-1$.

Step 3. Plot the coordinates.

The plot of the coordinate as shown below:
