Question

Quadrilateral RUST has a vertex at R (1,5)

what are the coordinates of R after translation (x,y) ---> (x+1,y-2), followed by a dilation by a scale factor of 3, centered at the origin?

A.(6,2)

B(5,8)


C(6,6)


D.(6,9)

Answer 1

D

Explanation

translation

x1 = x+1 = 2

y1 = y-2 = 3

(2;3)

dilation

x1 = 3x = 6

y2 = 3y = 9

(6,9)
