Find a Direction Vector When Given Two Points - Pre-Calculus

Card 0 of 14

Question

Find the directional vector of if points A and B are and , respectively.

Answer

To find vector , the point A is the terminal point and point B is the starting point.

The directional vector can be determined by subtracting the start from the terminal point.

Question

Find the vector through the points

and .

Answer

The correct vector is given by the subtraction of the two points: .

Since the subtraction here is component-wise, it is given by the formula: .

This results in the vector .

The vector is also correct as it is a scalar multiple of the vector marked as correct, it is found by reversing the order of the subtraction of the two points.
