Reflection rule over the line y = -x

Depends

Step-by-step explanation:

The reflection rule in y = x is as follows:

If you have the points (3,2) and (9,8), a reflection over y = x would look like this:

(3,2) -> (-2,-3)'

(9,8) -> (-8,-9)'

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
