I can understand and communicate fluently in your language of choice. I can also help you with various tasks such as writing, rewriting, improving, or optimizing your content.

To answer your question, you need to multiply the coordinates of the vector a by -2. The formula is:

$$-2a = -2(a_x, a_y) = (-2a_x, -2a_y)$$

If a = (-1, 4), then:

$$-2a = -2(-1, 4) = (2, -8)$$

The coordinates of the vector -2a are (2, -8). I hope this helps.Ответь+подробно.+Найти+координаты+вектора+-2a+если+a(-1;4)
