hi
You have two points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )
A(2 ; 1) and B (17 ; - 17)
so : (-17 - 1 ) / (17 -2) = -18/ 15 = - 6*3 / 5*3 = -6/5
Addition property of equality
There are 10 possible number on the first wheel, their would be 9 possible on the second, 8 on the thrid, 7 on the frouth, and 6 on the fifth.
So, 10 * 9 * 8 * 7 * 6 = 30,240 possible combinations without repeating numbers.
The distribution is skewed to the right
