Question 2 (Multiple Choice Worth 1 points)

(01.02MC)Point A is located at negative 7 over 10 and point B is located at negative 2 over 10. What is the distance between points A and B?

negative 7 over 10 plus negative 2 over 10 = negative 9 over 10; therefore, the distance from A to B is absolute value of negative 9 over 10 equals 9 over 10 units
negative 7 over 10 plus negative 2 over 10 = negative 9 over 10; therefore, the distance from A to B is absolute value of negative 9 over 10 equals negative 9 over 10 units
negative 7 over 10 minus negative 2 over 10 = negative 5 over 10; therefore, the distance from A to B is absolute value of negative 5 over 10 equals 5 over 10 units
negative 7 over 10 minus negative 2 over 10 = negative 5 over 10; therefore, the distance from A to B is absolute value of negative 5 over 10 equals negative 5 over 10 units
