First find the slope and then use it to determine if the line is rising, falling, horizontal, or vertical:
1. 5-y=7+ 2/3x
m= means this line is
2. 2x+3y=4x+2y
m= means this line is
3. 3y+6=12x
m= means this line is
4. 4(2-y)=12
m= means this line is
5. 2y= 2/3 x - 14
m= means this line is
6. 6(x+2y) =9y
m= means this line is
7. 3x+6=12
m= means this line is

(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
