Math Problem Statement

Given a vector begins at (-2, 1) and ends at (3, -4) then the components of the vector are

Solution

To find the components of the vector that begins at point (2,1)(-2, 1) and ends at point (3,4)(3, -4), we subtract the coordinates of the starting point from the coordinates of the ending point.

The formula for finding the components of the vector is: Vector components=(x2x1,y2y1)\text{Vector components} = (x_2 - x_1, y_2 - y_1) where (x1,y1)(x_1, y_1) is the starting point and (x2,y2)(x_2, y_2) is the ending point.

Substituting the given points: x1=2,y1=1x_1 = -2, \quad y_1 = 1 x2=3,y2=4x_2 = 3, \quad y_2 = -4

Now, calculate the components: Vector components=(3(2),41)\text{Vector components} = (3 - (-2), -4 - 1) Vector components=(3+2,41)\text{Vector components} = (3 + 2, -4 - 1) Vector components=(5,5)\text{Vector components} = (5, -5)

So, the components of the vector are (5,5)(5, -5).
