Triangle abc has vertices at a(−3, 4), b(4, −2), c(8, 3). the triangle translates 4 units right and 3 units down. which rule represents the translation? after the translation, what are the coordinates of vertex a? a) (x, y) → ( x + 4, y + 3); (1, 7) b) (x, y) → (x + 4, y − 3); a(1, 1) c) (x, y) → (x − 4, y + 3); (−7, 1) d) (x, y) → (x − 4, y − 3); a(1, −1)

B

Step-by-step explanation:

A translation of 4 units to the right, means add 4 to the original x- coordinate.

A translation of 3 units down, means subtract 3 from the original y- coordinate

Thus the rule is

(x, y ) → (x + 4, y - 3 ), hence

A(- 3, 4 ) → A'(- 3 + 4, 4 - 3 ) → A'(1, 1 )

b

step-by-step explanation:

the word superfluous means unnecessary

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
