What is the image of (7,8) after a reflection over the line y = –x

(-7. -8) Just flip the signs.

Step-by-step explanation:

When a point is reflected over y=-x, the following change occurs:

   ⇒  

We are given the point (7,8).

Essentially, we change the signs for both coordinates, then flip the x-coordinate and y-coordinate.

1. Change the signs

   ⇒    

2. Flip the x and y coordinates

  ⇒    

So the image of (7,8) after a reflection over y=-x is (-8,-7)

168

step-by-step explanation:

i am pretty sure that the answer is 168

5+2x=a
