Question

q. triangle ghi is reflected across the x - axis. what are the coordinates of i?

Explanation:

Step1: Determine the original coordinates of point \( I \)

From the graph, the original coordinates of point \( I \) are \( (6,-2) \).

Step2: Apply the reflection rule across the \( x \)-axis

The rule for reflecting a point \( (x,y) \) across the \( x \)-axis is \( (x,-y) \).
For the point \( (6,-2) \), when we apply the rule \( (x,y)\to(x, - y) \), we substitute \( x = 6 \) and \( y=-2 \).
So, \( -y=-(-2) = 2 \).

Answer:

The coordinates of \( I' \) are \( (6,2) \).
