Question

Triangle RST has coordinates: R(-2, 1) S(-8, 2) T(-4, 5)Draw the translation of RST 8 units right and 4 units down on your recording sheet. what are the coordinates of R'? A. R'(-3, 6)B. R'(0, -2)C. R'(6, -3) D. R'(4, 1)

Answer 1

R' (6,-3)

Explanation

Step 1

Let

R(-2, 1)

S(-8, 2)

T(-4, 5)

the law for the translation is 8 units right and 4 units down,it meas you have to add 8 units to x coordinates , and subtract 4 units from y coordinates

$(x,y)\rightarrow translation\rightarrow(x+8,y-4)$

Step 2

find the translation for R

$\begin{gathered} R(-2,1)\rightarrow translation\rightarrow R^{\prime}(-2+8,1-4)\rightarrow R^{\prime}(6,-3) \\ \end{gathered}$

so, the answer is C) R' (6,-3)
