Question

1 if triangle abc was reflected across the y - axis, what would be the coordinates of c?
(4, - 1)
(4,1)
(1,1)
(4, - 4)

Explanation:

Step1: Find the original coordinates of point C

From the graph, the coordinates of point C are \((- 4,1)\).

Step2: Apply the rule for reflection across the y - axis

The rule for reflecting a point \((x,y)\) across the y - axis is \((x,y)\to(-x,y)\).
For the point \(C(-4,1)\), when we apply the reflection rule \(x=-4\to -x = 4\) and \(y = 1\) remains the same.

Answer:

\((4,1)\) (corresponds to the second option)
