Question

The image of the point(-5,7) in Y axis has the coordinate *

Answer 1

Step-by-step explanation:

the image of the point - 57 in y axis has the coordinates

Answer 2

Answer:

The image of the point (-5,7) in Y axis has the coordinate (5,7).

Step-by-step explanation:

Under reflection of a point in the y-axis, the ordinate of the point remains unchanged while the sign of the abscissa is changed. So, the image of the point (x, y) in the y-axis is (−x, y).

Thus, the image of the point (−5, 7) in the y-axis is (5, 7).

By some other example we can easily understand this,

Let some other points (3,2),(6,-7),(8,9).

By the above rule the image of the point (3,2) in the y-axis is (-3,2).

The image of the point (6, -7) in the y-axis is (-6, -7)

and the image of the point (8, 9) in the y-axis is (-8,9).
