Find a formula for the transformation of reflection across the line l with equation y = -x.

The rule or formula for the transformation of reflection across the line l with equation y = -x will be:

P(x, y) ⇒ P'(-y, -x)

Step-by-step explanation:

Considering the point

If we reflect a point across the line with equation , the coordinates of the point P flips their places and the sign of the coordinates reverses.

Thus, the rule or formula for the transformation of reflection across the line l with equation y = -x will be:

P(x, y) ⇒ P'(-y, -x)

For example, if we reflect a point, let suppose A(1, 3), across the line with equation , the coordinates of point A flips their places and the sign of the coordinates reverses.

Hence,

A(1, 3) ⇒ A'(-3, -1)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
