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
To find the new points after reflecting a line across the y-axis, we simply change the x-coordinates of the points while keeping the y-coordinates the same.
The original points are (6, -3) and (3, 1).
When we reflect across the y-axis, the x-coordinate changes sign, but the y-coordinate remains the same.
So, the two new points after reflecting across the y-axis are:
(-6, -3) and (-3, 1).
