Given:

A vector from (-3.7,2) to (-4, -5).

To find:

An ordered pair that represents the vector

Solution:

If
(x_1,y_1) is the initial point and
(x_2,y_2) is the terminal point of a vector, then ordered pair that represents the vector is:


(x_2-x_1,y_2-y_1)

A vector from (-3.7,2) to (-4, -5). So, the ordered pair that represents the vector is:


(x_2-x_1,y_2-y_1)=(-4-(-3.7),-5-2)


(x_2-x_1,y_2-y_1)=(-4+3.7,-7)


(x_2-x_1,y_2-y_1)=(-0.3,-7)

Therefore, the correct option is b, i.e., (-0.3,-7).
