Given ABCD with A = (1,1),B = (4, 2), C = (4, 5), and D = (1, 4),what are the coordinates for Point D' if the y-axis is the reflecting line?
reflect through y-axis takes (x,y) --> (-x,y)
So, D(1,4) --> D'(-1,4)
Don't know why all the nonsense about ABC unless there are other problems relating to the figure.
To find the coordinates for Point D' if the y-axis is the reflecting line, we need to reflect the point D across the y-axis.
The y-axis is the vertical line that passes through (0,0) and divides the coordinate plane into two equal halves.
To reflect a point across the y-axis, we need to negate the x-coordinate and keep the y-coordinate the same.
In this case, the coordinates for point D are (1, 4). To reflect D across the y-axis, we negate the x-coordinate, which gives us (-1, 4).
Therefore, the coordinates for Point D' when reflecting D across the y-axis are (-1, 4).
