Question

2 multiple choice 10 points right triangle lmn has vertices l(7, -3), m(7, -8), and n(10, -8). the triangle is translated on the coordinate plane so the coordinates of l are (-1, 8). which rule was used to translate the image? (x,y)→(x + 6,y - 5) (x,y)→(x - 6,y + 5) (x,y)→(x + 8,y - 11) (x,y)→(x - 8,y + 11)

Explanation:

Step1: Find change in x - coordinate

The x - coordinate of L is 7 and of L' is - 1. The change in x is $-1 - 7=-8$.

Step2: Find change in y - coordinate

The y - coordinate of L is - 3 and of L' is 8. The change in y is $8-(-3)=8 + 3 = 11$.

Step3: Determine the translation rule

The translation rule is $(x,y)\to(x - 8,y + 11)$ as we subtract 8 from the x - coordinate and add 11 to the y - coordinate.

Answer:

$(x,y)\to(x - 8,y + 11)$
