Question

Triangle TVW is dilated according to the rule
DO,(x,y)(three-fourths x, three-fourths y) to create the image triangle T'V'W', which is not shown.

On a coordinate plane, triangle T V W has points (negative 4, 8), (0, 4), and (4, 4).

What are the coordinates of the endpoints of the segment T'V'?

T'(-3, 6) and V'(0, 3)
T'(-3, 6) and V'(0, 1)
T'(-1, 2) and V'(0, 3)
T'(-1, 2) and V'(0, 1)

Answer 1

Scale each coordinate by 3/4 about the origin.

T' = (-4 * 3/4, 8 * 3/4) = (-3, 6)
V' = (0 * 3/4, 4 * 3/4) = (0, 3)

Answer: T'(-3, 6) and V'(0, 3).
