Hello,
Codes are :
5_6_7, 5_7_6
6_5_7,6_7_5
7_5_6,7_6_5
Choising the first (3 possibilities)
next choising the second (2 possibilities)
chosing the last (1 possibility)
So 3*2*1=6
Answer A
The slope of the line containing the points (2,3) and (9,7) is 4/7.
Slope Formula: y₂ - y₁ 7 - 3 4
------------- = ----------- = -------
x₂ - x₁ 9 - 2 7
4/7 can't be reduced any further, so that's your final answer.
