I would like an explanation, as well as the answer. Im trying to learn-
Trapezoid JKLM is shown on the coordinate plane below:

Trapezoid JKLM on the coordinate plane with ordered pairs at J negative 7, negative 2, at K negative 4, negative 2, at L negative 2, negative 5, at M negative 9, negative 5.

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

(1, −5)
(−10, 6)
(−5, 3)
(6, −8)

Respuesta :

This is really simple if you understand it.
The rule (x,y)--->(x+8)(y-3)  just tells you to add and subtract all 4 coordinates.

For example, the 1st coordinate -7,-2 . Add 8 to x (-7). 8-7 = 1  
Subtract -3 from y.  -2-3=-5

Answer:

The Answer is: (1, −5)
