helpppppp!!!!!

Answer 1

The answer is (-4,3) so C

Answer 2

`\boxed{\text{c) (-4, 3)}}`

Explanation:

When you reflect a point (x, y) across the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign: it becomes (-x, y).

Thus, if a point A, say, (4, 3) is reflected across the y-axis, its reflection A' is at

`\boxed{\textbf{(-4, 3)}}`
