is there a picture of a graph, or is a coordinate given?
you need to sub in the coordinates for y and x to solve for this
one.
or somehow get the gradient, and it will be equal to -k
no graph given... de qn should be wrong.. .too many
unknowns in one eqn.
by right it should acc. with another curve eqn.
i'll just ask tmr lah... my friends friends all
say it is high chance wrong even the Pro of de Pro said so...
lolz
nvm. thankx for de concern oso ^^
