Question

which point has coordinates (1, −2)?

Explanation:

Step1: Recall coordinate system rules

In a coordinate \((x, y)\), \(x\) is horizontal (right positive, left negative), \(y\) is vertical (up positive, down negative).

Step2: Analyze \(x = 1\)

Move 1 unit right from origin (0,0) along x - axis.

Step3: Analyze \(y=-2\)

Move 2 units down from \(x = 1\) position along y - axis.

Step4: Identify the point

Looking at the graph, point Q is at \(x = 1\), \(y=-2\) (matching \((1, - 2)\)). Point P: \(x=-2,y = 1\); Point R: \(x = 2,y=-1\); Point S: \(x=-1,y=-2\).

Answer:
