Find the image of a (-6, 5) after two reflections, first across the line y = -5, then across the line x = -12. write your answer for both reflections or show your graph with each step. (2 points) a. reflection 1: y = -5 : b. reflection 2: x = -12 :

a.

b.

Step-by-step explanation:

The given point is .

We want to find the image after this point has been reflected in the line .

Recall that, the mapping for a reflection in the line is

.

This implies that,

.

This simplifies to,

.

This will finally give us,

.

b. We now apply the second reflection, which is a reflection in the line .

Recall again that, the reflection in the line has the mapping

.

This implies that,

.

This implies that,

.

This will finally give us,

.

See graph in attachment.

b.an increase in a causes b to decrease

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
