the cartesian plan
identify the ordered pair for each of the points on the graph.
an example of a pair is in the form (1,2).
label: ordered pair
a: enter your answer
b: enter your answer
c: enter your answer

Explanation:

Step1: Recall ordered - pair concept

In a Cartesian plane, an ordered pair $(x,y)$ represents a point where $x$ is the horizontal (abscissa) and $y$ is the vertical (ordinate) distance from the origin.

Step2: Determine point A

For point A, moving horizontally from the origin, we see it is at $x = 10$ and vertically at $y=- 8$. So the ordered - pair is $(10,-8)$.

Step3: Determine point B

For point B, horizontally it is at $x = 12$ and vertically at $y = 2$. So the ordered - pair is $(12,2)$.

Step4: Determine point C

For point C, horizontally it is at $x = 13$ and vertically at $y=-11$. So the ordered - pair is $(13,-11)$.

Step5: Determine point D

For point D, horizontally it is at $x = 0$ and vertically at $y = 12$. So the ordered - pair is $(0,12)$.

Step6: Determine point E

For point E, horizontally it is at $x=-9$ and vertically at $y = 3$. So the ordered - pair is $(-9,3)$.

Answer:

A. $(10,-8)$
B. $(12,2)$
C. $(13,-11)$
D. $(0,12)$
E. $(-9,3)$
