Question

Если А(-2;4) и В(1;-3), то вектор АВ имеет координаты помогите пожалуйста

Answer 1

АВ(х2-х1; у 2-у1)
АВ(1-(-2); -3-4)
АВ(3; -7)

Answer 2

Calculating the Vector AB

To find the vector AB with points A(-2, 4) and B(1, -3), we can use the formula for the vector between two points:

AB = B - A

Substitute the coordinates of points A and B into the formula:

AB = (1, -3) - (-2, 4)

This gives us:

AB = (1 - (-2), -3 - 4) = (3, -7)

So, the vector AB has the coordinates (3, -7).
