Final answer:
To find the new endpoints of the segment after it is translated, add 6 to the x-coordinate and subtract 3 from the y-coordinate of each endpoint.
Step-by-step explanation:
endpoints of the segment after it is translated with the rule (x,y) -> (x + 6, y - 3), we need to add 6 to the x-coordinate of each endpoint and subtract 3 from the y-coordinate of each endpoint.
For the endpoint M(2,5), the new endpoint will be (2 + 6, 5 - 3) = (8, 2).
For the endpoint N(8,-1), the new endpoint will be (8 + 6, -1 - 3) = (14, -4).
So, the new endpoints of the segment are M(8,2) and N(14,-4).
