Question

If trapezoid JKLM is translated according to the rule (x, y) -> (x + 8, y - 3), what are the coordinates of point L'?

A. (1, -5)

B. (-10, 6)

C. (-5, 3)

D. (6, -8)​

Answer 1

D.

Explanation:

First step: Identify the point for L.

L is at (-2,-5).

We are plugging this (x,y) into (x+8,y-3) to see where it takes us.

(-2+8,-5-3)=(6,-8).

The solution is D.

Answer 2

Answer: OPTION D

Explanation:

You can observe in the figure that the coordinates of the point L are:

`L(-2,-5)`

You know that the trapezoid rule applied for the translation of the trapezoid JKLM is:

`(x, y)`→
`(x + 8, y - 3)`

Therefore, in order to find the coordinates of the point L', you need to add 8 to the x-coordinate of the point L and subtract 3 from the y-coordinate of the point L.

Then:

`L'(-2 + 8, -5 - 3)\\\\L'(6,-8)`
