Question

Triangle STU below is translated right 2 units and 3 units down. What are the coordinates of the vertices of the image?

A. S’(−9, 12), T’(−12, 5), U’(−6, 5)
B. S’(−4, 7), T’(−7, 0), U’(−1, 0)

C. S’(−8, 13), T’(−11, 6), U’(−5, 6
)
D. S’(−4, 10), T’(−7, 3), U’(−1, 3)

Answer 1

What is the transformation?

Answer 2

@meilendurcer it does not look like the question is complete.

Answer 3

one sec i think your right.

Answer 4

Right 2 units you add 2 to the x coordinate, down 3 units you subtract 3 from the y coordinate

Answer 5

so B or C?

Answer 6

Good try, now do exactly what you said to the point S and see which choice matches.

Answer 7

S has coordinates (-6,10), so add 2 to x, and subtract 3 from y.

Answer 8

ahh D then

Answer 9

What do you get?

Answer 10

none of it

Answer 11

What did you get for S'?

Answer 12

can't you just tell me the answer please? i need this in tonight

Answer 13

@mathmate

Answer 14

(-6,10) -> (-6+2, 10-7) = ?

Answer 15

-7?

Answer 16

In (-6,10), -6 is the x-coordinate, and 10 is the y-coordinate.
So a translation 2 units to the right means add 2 to -6, and 3 units down means subtract 3 from 10.
So the new coordinates for S is
S'(-6+2, 10-3) =S'(-4,7)
Can you find your answer now?

Answer 17

-11?

Answer 18

Your answer has to be one of the choices of a, b, c or d.
Look at the coordinates of S' in each of the choices. If there is a match in only one case, that's the answer. If there is a match of S'(-4,7) in more than one choice, you would have to repeat the same calculations for T' to distinguish between the possible choices.

Answer 19

ok yay it's A

Answer 20

Sorry it's not A.

Answer 21

then i was right D?

Answer 22

What was the answer?
