Question

Triangle PQR has coordinates P(–8, 3), Q(–8, 6), and R(–3, 6). If the triangle is translated by using the rule (x, y) right-arrow (x + 4, y minus 6), what are the coordinates of triangle P prime Q prime R prime? (a)P prime (negative 12, 9), Q prime (negative 12, 12), R prime (negative 7, 12) (b)P prime (negative 4, 7), Q prime (negative 14, 0), R prime (1, 10) (c)P prime (negative 4, 9), Q prime (negative 4, 12), R prime (1, 12) (d)P prime (negative 4, negative 3), Q prime (negative 4, 0), R prime (1, 0)

Answer 1

D

Explanation:

Answer 2

d

Explanation:

The rule (x, y ) → (x + 4, y - 6 )

means add 4 to the original x- coordinate and subtract 6 from the original y- coordinate, thus

P(- 8, 3 ) → P'(- 8 + 4, 3 - 6 ) → P'(- 4, - 3 )

Q(- 8, 6 ) → Q'(- 8 + 4, 6 - 6 ) → Q'(- 4, 0 )

R(- 3, 6 ) → R'(- 3 + 4, 6 - 6 ) → R'(1, 0 )
