    Answer:

    (3,5) = (-3,5)

    (-2,-4) = (2, -4)

    Step-by-step explanation:

    All you have to do is change the X  into the opposite value

    Answer:

    The co-ordinates of the points (3, 5) and (-2, -4) after reflection are (-3, 5) and (2, -4) respectively.

    Step-by-step explanation:

    Given that on a co-ordinate grid,  both point (3, 5) and point (−2, −4) are reflected across the y-axis.

    We are to find the co-ordinates of the reflected points.

    We know that

    if a point with co-ordinates (x, y) is reflected across y-axis, then the sigh before the x co-ordinate changes.

    That is,

    (x, y)  —–>  (-x, y).

    Therefore, the the co-ordinates of the point (3, 5) after reflection is (-3, 5).

    And, the co-ordinates of the point (-2, -4) after reflection is (2, -4).

    Thus, the co-ordinates of the points (3, 5) and (-2, -4) after reflection are (-3, 5) and (2, -4) respectively.
