# Recognizing vectors practice

Try two questions that make sure you understand that vectors have magnitude and direction.

## Problem 1

Which of the following can represent a vector?
A vector is a quantity that can be described as having both magnitude and direction.
The length of the distance between any two points is a magnitude with no direction, so it can't represent a vector.
A line segment beginning at a certain point and ending at another can represent a vector. The magnitude of the vector is the distance between the points, and its direction is the direction from the initial point to the terminal point.
The following can represent a vector:
• A line segment beginning at left parenthesis, 0, comma, 0, right parenthesis and ending at left parenthesis, 2, comma, 7, right parenthesis
• A line segment beginning at left parenthesis, 2, comma, 7, right parenthesis and ending at left parenthesis, 0, comma, 0, right parenthesis

## Problem 2

Which of the following can be modeled by a vector?
