Complete the mapping of the vertices of δdef. d(2, –4) → d' e(1, –1) → e' f(5, 1) → f' what is the rule that describes a reflection across the line y = x? rx = y(x, y) →

The rule of reflection across the line y = x is

The mapping of the vertices of ΔDEF is given by :-

Step-by-step explanation:

When we reflect a point across the line y = x, the x-coordinate and y-coordinate interchanges places.

The rule of reflection across the line y = x is

Then, the mapping of the vertices of ΔDEF is given by :-

what?

what do you need with. i love quadrants. can you tell me ?
