Question

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)

Answer 2

The rule used to translate the image is $(x,y) \to (x-8, y+11)$.

In this question we are going to speak of point translations. Vectorially speaking, a translation between two points is defined by this expression:

$L'(x,y) = L(x,y) + T(x,y)$  (1)

Where:

• $L(x,y)$ - Original point.
• $T(x,y)$ - Translation vector.
• $L'(x,y)$ - Translated point.

If we know that $L(x,y) = (7, -3)$ and $L'(x,y) = (-1, 8)$, then the translation vector is:

$T(x,y) = L'(x,y) - L(x,y)$

$T(x,y) = (-1,8)-(7,-3)$

$T(x,y) = (-8, 11)$

Therefore, the rule used to translate the image is $(x,y) \to (x-8, y+11)$.
