Question

1. which coordinates represent $p_1$ and $p_2$, respectively, in the coordinate plane below?

$p_1(-2,2)$ and $p_2(-2,4)$
$p_1(2,4)$ and $p_2(1,-2)$
$p_1(4,2)$ and $p_2(-2,1)$
$p_1(4,-2)$ and $p_2(2,1)$

Explanation:

Step1: Locate P1 on the graph

For point P1, move 4 units to the right along the x - axis and 2 units up along the y - axis from the origin. So the coordinates of P1 are (4, 2).

Step2: Locate P2 on the graph

For point P2, move 2 units to the left along the x - axis and 1 unit up along the y - axis from the origin. So the coordinates of P2 are (-2, 1).

Answer:

P1(4,2) and P2(-2,1)
