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