What is the equation of the line passing through the points (2, –1) and (5, –10) in slope-intercept form?
y = negative 3 x minus 5
y = negative 3 x + 5
y = 3 x minus 5
y = 3 x + 5

The equation of the line is y = -3x + 5 "i.e. negative 3x + 5"

(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
