A landscaper will install a sprinkler system for a client and has shown on a coordinate grid the location of the main water line for the system. The line will run from point S(a, −4) to point E(29, b).



Which expression represents the shortest distance between points S and E?


(a+4)2 + (29−b)2(a+4)2 + (29−b)2

(a+4)2 + (29−b)2−−−−−−−−−−−−−−−−−√(a+4)2 + (29−b)2−−−−−−−−−−−−−−−−−√

(29−a)2 + (b+4)2−−−−−−−−−−−−−−−−−√
