Question

Trapezoid JKLM is shown on the coordinate plane below:

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

1. (1, −5) 
2. (−10, 6) 
3. (−5, 3) 
4. (6, −8)

Answer 1

Current location (pre-image) of point L: ( -2 , -5 )

x --> x + 8 --> (-2) + 8 = 6

y --> y-3 --> (-5) - 3 = -8

L' = ( 6 , -8 )

So (4) is the correct answer choice.
