well at y=-5, x = 0 now you have two coordinate points at (0,-5) ; and (2,7) gradient or slope = y2-y1/x2-x1 = 7-(-5)/2-0 = 12/2 = 6 ------------> therefore m=6 now to find the equation we use this formula: y-y1=m(x-x1) take any set of the two points (in this case i am taking (2,7) y-7 = 6(x-2) then y-7 = 6x-12 y=6x-12+7 -------------> y=6x+5

not covalent bonding, not ionic bonding, and therefore it is definately hydrogen bonding which is the weakes bond between molecules.

hydrogen bonding is the weakest.
