Question 8(Multiple Choice Worth 1 points)
(01.02 MC)Point A is located at negative 5 over 8 and point B is located at negative 2 over 8. What is the distance between points A and B?

negative 5 over 8 minus negative 2 over 8 = negative 3 over 8 ; therefore, the distance from A to B is absolute value of negative 3 over 8 equals 3 over 8units
negative 5 over 8 minus negative 2 over 8 = negative 3 over 8 ; therefore, the distance from A to B is absolute value of negative 3 over 8 equals negative 3 over 8 units
negative 5 over 8 plus negative 2 over 8 = negative 7 over 8; therefore, the distance from A to B is absolute value of negative 7 over 8 equals 7 over 8 units
negative 5 over 8 plus negative 2 over 8 = negative 7 over 8; therefore, the distance from A to B is absolute value of negative 7 over 8 equals negative 7 over 8 units
