Question

question 1 of 10
if \\( \triangle a b c \\) is reflected across the \\( y \\)-axis, what are the coordinates of \\( a \\)?
a. \\( (4,-2) \\)
b. \\( (4,2) \\)

Explanation:

Step1: Find the original coordinates of point A

From the graph, the coordinates of point A are \((-4,2)\).

Step2: Apply the reflection rule across the y - axis

The rule for reflecting a point \((x,y)\) across the y - axis is \((-x,y)\).
For point \(A(-4,2)\), when we apply the rule \(x=-(-4) = 4\) and \(y = 2\) remains the same.

Answer:

B. \((4,2)\)
