Forklaring:
# "den korteste afstand fra et punkt" (m, n) "til en" #
# "linje" Ax + By + C = 0 "er givet ved" #
# • farve (hvid) (x) d = | Am + Bn + C | / (sqrt (A ^ 2 + B ^ 2) #
# "her" (m, n) = (3,5) #
# "udtrykker ligningen i den rigtige form giver" #
# 3x + 2y-6 = 0 #
# "med" A = 3, B = 2 "og" C = -6 #
# D = | (3xx3) + (2xx5) -6 | / (sqrt (3 ^ 2 + 2 ^ 2) #
#color (hvid) (d) = 13 / sqrt13 ~~ 3.606 "til 3 dec. steder" #
