Example Questions

Example Question #1 : Find A Direction Vector When Given Two Points

Find the vector through the points

(12,5) and (-4,22) .

Possible Answers:

<8,27>

<16,-17>

<16,17>

<8,17>

<-16,27>

Correct answer:

<16,-17>

Explanation:

The correct vector is given by the subtraction of the two points: (12,5)-(-4,22) .

Since the subtraction here is component-wise, it is given by the formula: <x_1-x_2,y_1-y_2> .

This results in the vector <16,-17> .

The vector <-16,17> 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.
