CAN SOMEONE HELP ME PLEASE ILL GIVE BRAINLEST..I need step to step equation thanks​

Answer 1

Answer:

The required co-ordinate is (-2, -5).

Step-by-step explanation:

For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: $R_{y = k} = (x, 2k - y)$.

Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:

$R_{y = 1} (-2, 7) = (-2, 2(1) - 7)$

= (-2, -5)

The reflected point is (-2, -5).
