A line contains the points (6, -3) and (3,1). When this line is reflected across the y-axis what are the two new points
When reflecting a point across the y-axis, the x-coordinate of the point becomes its opposite while the y-coordinate remains the same.
Given the points (6, -3) and (3, 1), when these points are reflected across the y-axis, the x-coordinate of each point will become its opposite, while the y-coordinate remains the same.
For the point (6, -3), the new point after reflecting across the y-axis will be (-6, -3).
For the point (3, 1), the new point after reflecting across the y-axis will be (-3, 1).
Therefore, the two new points after reflecting the line across the y-axis are (-6, -3) and (-3, 1).
