What will be the location of the x value of R' after using the translation rule (x + 4, y - 7), if the pre-image R is located at ( 24, -13)

Answer 1

Answer: The x value is x = 28

Point R' is located at (28, -20)

=========================================================

Reason:

The translation rule is
`(\text{x},\text{y})\to (\text{x}+4,\text{y}-7)`

It says to add 4 to the x coordinate, and subtract 7 from the y coordinate.

If we apply the rule to point R(24, -13), then we have...

`(\text{x},\text{y})\to (\text{x}+4,\text{y}-7)\\\\(24,-13)\to (24+4,-13-7)\\\\(24,-13)\to (28,-20)\\\\`

This rule shifts the point 4 units to the right and 7 units down.
