Question

which coordinate is the same as the x - coordinate of point a? y - coordinate of point a which coordinate is the same as the y - 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: Identify coordinates

Point \( A(-1,2) \), so \( x \)-coordinate of \( A \) is \( -1 \), \( y \)-coordinate of \( A \) is \( 2 \). Point \( A'(2,1) \), so \( y \)-coordinate of \( A' \) is \( 1 \).

Step2: Analyze options

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

eq1 \).

• \( y \)-coordinate of \( A \) is \( 2

eq1 \).

• Opposite of \( x \)-coordinate of \( A \) is \( -(-1)=1 \), which is equal to \( y \)-coordinate of \( A' \).
• Opposite of \( y \)-coordinate of \( A \) is \( -2

eq1 \).

Answer:

Opposite of \( x \)-coordinate of point \( A \)
