Question

Which of the following represents the translation of A (1, -2) along the vector <-3, 2> and then the vector < 0, -4>.?

Answer 1

The correct option is the last one: A(1, -2) A'(-2, 0) A''(-2, -4)

To translate a figure along a vector, we add coordinate to coordinate.

The figure is A(1, -2), the first vector is <-3, 2> then:

`A^(\prime)(1-3,-2+2)=A^(\prime)(-2,0)`

From A'(-2, 0) we move along <0, -4>

`A^(\prime)^(\prime)(-2+0,0-4)=A^(\prime)^(\prime)(-2,-4)`

Thus, the correct answer is the last option
