Chapter 3, Problem 391RE

In the following exercises, plot each point in a rectangular coordinate system.

391.

(a) $\left(-1,-5\right)$

(b) $\left(-3,4\right)$

(c) $\left(2,-3\right)$

(d) $\left(1,\frac{5}{2}\right)$

To determine

(a)

Plot given point in the rectangular coordinate system.

Answer to Problem 391RE

Explanation of Solution

Given information:

Ordered pair $(-2,0)$

Calculation:

Given an ordered pair $(-2,0)$. We must plot this point in a rectangular coordinate system.

The first number of the coordinate pair is $x-$ coordinate, and the second number is the $y-$ coordinate.

Since $y=0$, The point $(-2,0)$ is on the $x-$ axis.

Now let’s draw this point in a rectangular coordinate system using desmos graph calculator.

To determine

(b)

Plot given point in the rectangular coordinate system.

Answer to Problem 391RE

Explanation of Solution

Given information:

Ordered pair $(0,-4)$

Calculation:

Given an ordered pair $(0,-4)$. We must plot this point in a rectangular coordinate system.

The first number of the coordinate pair is $x-$ coordinate, and the second number is the $y-$ coordinate.

Since $x=0$, The point $(0,-4)$ is on the $y-$ axis.

Now let’s draw this point in a rectangular coordinate system using desmos graph calculator.

To determine

(c)

Plot given point in the rectangular coordinate system.

Answer to Problem 391RE

Explanation of Solution

Given information:

Ordered pair $(0,5)$

Calculation:

Given an ordered pair $(0,5)$. We must plot this point in a rectangular coordinate system. The first number of the coordinate pair is $x-$ coordinate, and the second number is the $y-$ coordinate.

Since $x=0$, The point $(0,5)$ is on the $y-$ axis.

Now let’s draw this point in a rectangular coordinate system using desmos graph calculator.

To determine

(d)

Plot given point in the rectangular coordinate system.

Answer to Problem 391RE

Explanation of Solution

Given information:

Ordered pair $(3,0)$

Calculation:

Given an ordered pair $(3,0)$. We must plot this point in a rectangular coordinate system.

The first number of the coordinate pair is $x-$ coordinate, and the second number is the $y-$ coordinate.

Since $y=0$, The point $(3,0)$ is on the $x-$ axis.

Now let’s draw this point in a rectangular coordinate system using desmos graph calculator.
