Which of the following is the equation of a line in slope-intercept form for a
line with slope = 1 and y-intercept at (0,-4)?

y = x - 4

Step-by-step explanation:

y = mx + b

y = (1)x + (-4)

(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
