The point ( -1.5,-2) is reflected across the y-axis, What are the coordinates of the point after the reflection?
WHAT S THE ANSWER
To find the coordinates of a point after reflecting it across the y-axis, you need to change the sign of its x-coordinate while leaving the y-coordinate unchanged.
In this case, the original point is (-1.5, -2). To reflect it across the y-axis:
1. Change the sign of the x-coordinate, so -1.5 becomes 1.5.
2. Keep the y-coordinate unchanged, which is -2.
So, after reflecting the point (-1.5, -2) across the y-axis, the new coordinates are (1.5, -2).
well, such a reflection takes
(x,y) -> (-x,y)
Now just plug in your numbers.
