Question

which coordinate is the same as the x - coordinate of point a? x - coordinate of point a y - coordinate of point a opposite of x - coordinate of point a opposite of y - coordinate of point a

Explanation:

Step1: Find the x - coordinate of point \(A\)

Given \(A(-1,2)\), the \(x\) - coordinate of point \(A\) is \(-1\).

Step2: Find the x - coordinate of point \(A'\)

Given \(A'(2,1)\), the \(x\) - coordinate of point \(A'\) is \(2\).

Step3: Analyze each option

• Option 1: \(x\) - coordinate of \(A\) is \(-1

eq2\).

• Option 2: \(y\) - coordinate of \(A\) is \(2\), but we are comparing \(x\) - coordinates.
• Option 3: Opposite of \(x\) - coordinate of \(A\): The opposite of \(-1\) is \(1

eq2\).

• Option 4: Opposite of \(y\) - coordinate of \(A\): The \(y\) - coordinate of \(A\) is \(2\), and its opposite is \(- 2\). Wait, no. Wait, actually, if we consider the problem again. Wait, the \(x\) - coordinate of \(A'\) is \(2\). The \(y\) - coordinate of \(A\) is \(2\).

Answer:

\(y\) - coordinate of point \(A\)
