What is the slope of the line that passes through (1, -5) and (3, -8)?

The slope would be -3/2

Step-by-step explanation:

To get the numerator of the slope you would do -8-(-5) to get -3. To get the denominator, you would do 3-1 to get 2. That would leave you with the final answer of slope -3/2.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
