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 \(x\) - coordinate of \(A'\)

From \(A'(2,1)\), \(x\) - coordinate is \(2\).

Step2: Find \(x\) - coordinate of \(A\)

From \(A(-1,2)\), \(x\) - coordinate is \(-1\).

Step3: Find \(y\) - coordinate of \(A\)

From \(A(-1,2)\), \(y\) - coordinate is \(2\).

Step4: Find opposite of \(x\) - coordinate of \(A\)

Opposite of \(-1\) is \(1\).

Step5: Find opposite of \(y\) - coordinate of \(A\)

Opposite of \(2\) is \(-2\).

Answer:

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