Question

In the graph below, line "k" y = -k makes a 45° angle with the x- and y- axes. Rx:

Answer 1

B(-2,5) I'm just guessing

Answer 2

Answer with explanation:

In two dimensional plane, a line y=-x, is drawn. A point ,(2,5) is shown in the coordinate plane.

When the point, Preimage  (2,5) is reflected through, line , y= -x

the coordinates of image , that is point after reflection will be (-5, -2).

The rule says that if you will reflect a point , (a,b) through line, y= -x, the coordinates of point after reflection will be , (-b, -a).

⇒(2,5) after reflection = (-5, -2).
