What is the rule for finding the coordinates of an image reflected over the line y=-x?
a. (x, y) →(-y,-x)
b. (x, y)→(y, x)
c. (x, y)→(y,-x)
d. (x, y)→(x,-y)

A.

Step-by-step explanation:

We are asked to find the rule for finding the coordinates of an image reflected over the line .

We know that the after reflection across the line the x- and y-coordinates of a point interchanges places and their signs are also changed.

This means that rule of reflection across the line is , therefore, the option A is the correct choice.

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
