Question

REFLECTIONS!!!!! if P= (-2,7) find: Rx=1 (P) SOMEONE PLEASE HELP ​

Answer 1

Answer:


`R_(x=1)(P)=(4,7)`

Explanation:

The given point P has coordinates,
`(-2,7)`.

We want to find the image of this point, after a reflection in the line
`x=1`.

The mapping for a reflection in the line,
`x=k` is


`(x,y)\to (2k-x,y)`

This implies that;


`(-2,7)\to (2(1)--2,7)`

Hence;


`(-2,7)\to (4,7)`
