Answer:
The coordinates of the image point will be (-2,-4).
Step-by-step explanation:
The reflection of the point (2,-4) over the y-axis is to be determined.
Now, as the reflecting mirror is the y-axis, then the y-coordinate of the reflecting point will not change.
So, the image point will have coordinates (h,-4).
Now, after the reflection over the y-axis, the x-coordinate of the image point will change the sign only compared to the original point.
Therefore, the coordinates of the image point will be (-2,-4). (Answer)
(9√25) /√50 = 9*5/√50 now simplify the denominator. √50=√25*√2=5√2
so (9*5)/(5√2) simplifies to 9/√2. To rationalize the denominator multiply both the numerator and the denominator by √2.
9√2/(√2*√2) = 9√2/2
