Exercise 23 Page 707

The component form of a vector is ⟨ x_2-x_1,y_2-y_1 ⟩.

⟨ 6,3 ⟩

We use the component form of a vector to describe the vector in terms of its horizontal component x and vertical component y. ⟨ x,y ⟩

To write the component form of a vector with initial point (x_1,y_1) and terminal point (x_2,y_2), we need to find ⟨ x_2-x_1,y_2-y_1 ⟩. Let's identify the initial and terminal points of the given vector. Remember, the initial point is written as a dot, while the terminal point is shown as an arrow.

Now, we can substitute these values into the component form of a vector and simplify.

BC = ⟨ x_2-x_1,y_2-y_1 ⟩

SubstitutePoints

Substitute ( -2,-2) & ( 4,1)

BC = ⟨ 4-( -2), 1-( -2) ⟩

a-(- b)=a+b

BC = ⟨ 4+2,1+2 ⟩

Add terms

BC = ⟨ 6,3 ⟩
