Santos Vang · Answer 1

R (1/3, 1), S (2, 4/3), T (4/3, 2/3)

Step-by-step explanation:

Dilation by a factor of 3 about the origin multiplies each coordinate by 3. To find what was multiplied by 3 to get the given coordinates, we divide the given coordinates by 3.

William Christensen · Answer 2

R (1/3,1)

S = (2,4/3)

T = (4/3,2/3)

Step-by-step explanation:

RST becomes R'S'T' by multiplying by 3

To get back to RST we need to divide by 3

R = (1/3, 3/3) = (1/3,1)

S = (6/3,4/3) = (2,4/3)

T = (4/3,2/3)
