Find the image of (3,6) reflected across the y-axis
well, for any (x,y) the transformation is
(x,y) -> (-x,y)
To find the image of a point reflected across the y-axis, we need to change the sign of the x-coordinate.
Given the point (3, 6), to reflect it across the y-axis, we change the sign of the x-coordinate.
So, the image of (3,6) reflected across the y-axis is (-3, 6).
To find the image of a point reflected across the y-axis, you simply need to change the sign of the x-coordinate while keeping the y-coordinate the same.
Given the point (3,6), we can reflect it across the y-axis by changing the sign of the x-coordinate to -3, while keeping the y-coordinate 6 unchanged.
Therefore, the image of point (3,6) reflected across the y-axis is (-3,6).
