To be divisible by 63, it must be divisible by both 7 and 9, since 7x9 = 63. Factor the expression, simplify, and see if both 7 and 9 are factors, which would make it divisible by both 7 and 9. (163 - 83)(43 + 23) = [(24)3 - (23)3] [(22)3 + 23] = (212 - 29)(26 + 23) = [29(23 - 1)] [23(23 + 1)] = [29(8 - 1)] [23(8 + 1)] = 29(7) 23 (9) = 63(212) It is a multiple of 63, and hence divisible by 63.

Step 1
4n−m+3p+2m−n−p Equation
Step 2
4n−m+3p+2m−n−p Simplify by combining terms
(-m+2m)+(4n+-n)+(3p+-p)
Step 3
(-m+2m)+(4n+-n)+(3p+-p) Add them together
m+3n+2p
Answer
m+3n+2p
The slope is negative and is -16 / 8 = -2
The y intercept is at y = 16
General form is y = mx + c
m = -2 and c = 16 so we have :-
y = -2x + 16 Answer
