Find the slope of the y intercept of the graph linear equation 2x+y=7

2x+y=7

-2x       -2x

y=-2x+7

slope of -2

Hope this is right, feel free to correct me in the comments

-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
