Best ResponseYou've already chosen the best response.3The distance between any two points on a number line is the absolute value of the difference of their coordinates. For points with coordinates a and b, the distance between them is \(a  b \).

Best ResponseYou've already chosen the best response.3Correct. Just add. Also it makes no difference which point you use first and which you use second. The absolute value makes sure the answer is always positive, which any distance is. 19  (39) = 19 + 39 = 58 = 58 39  19 = 58 = 58
