Question

rapezoid 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 NC 3), what are the coordinates of point L'?

(1, -5)

(-10, 6)

(-5, 3)

(6, -8)

Answer 1

@AccessDenied i need help with this one pleease

Answer 2

What does "y NC 3" mean?

I believe you just have to apply the rule (x,y) --> (x+8, y "NC" 3) to the point L to find L'.
L(-2,-5) --> L'(-2+8, -5 "NC" 3)

Answer 3

I guess since all the x-values for the choices are unique, it's easy to spot it without knowing the y-value's operation though.
(-2 + 8, -5 "NC" 3)
(6, -5 "NC" 3)
I can only assume the NC is subtraction to match the one answer with x=6, (6,-8)

Answer 4

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

thats what my question has

Answer 5

same exact question with the same options

Answer 6

yeah, so applying the rule (x,y) --> (x+8, y - 3) to the point L(-2,-5):
L'(-2+8, -5-3) = L'(6, -8)

Basically, since it's just a translation and we're given the rule, we just have to plug in the (x,y) point we're translating and we should get the (x',y') translated point out.

Answer 7

oh okaay thanks thats actually what i had chosen i was just making sure

Answer 8

You're welcome. :)
