Question

1. graph each of the following ordered pairs on the coordinate plane and name the quadrant in which they are located.

(2, 1), quadrant
(-2, 1), quadrant
(-2, -1), quadrant
(2, -1), quadrant
what shape can you make by connecting

Explanation:

Step1: Recall quadrant sign rules

Quadrant I: $(+, +)$; Quadrant II: $(-, +)$; Quadrant III: $(-, -)$; Quadrant IV: $(+, -)$

Step2: Match (2,1) to quadrant

$(2,1)$ is $(+, +)$, so Quadrant I

Step3: Match (-2,1) to quadrant

$(-2,1)$ is $(-, +)$, so Quadrant II

Step4: Match (-2,-1) to quadrant

$(-2,-1)$ is $(-, -)$, so Quadrant III

Step5: Match (2,-1) to quadrant

$(2,-1)$ is $(+, -)$, so Quadrant IV

Step6: Identify shape from points

Connecting these four points (right angles, equal side lengths) forms a square.

Answer:

(2, 1), Quadrant I
(-2, 1), Quadrant II
(-2, -1), Quadrant III
(2, -1), Quadrant IV
The shape formed by connecting the points is a square.
