1. Soln:- Here,
given equation is
-8x=5y+7
y=(-8x/5) -7/5 ------(1)
For direct variation we have:
y=kx where k is the constant of variation.
since the equation (1) not in form of y=kx ,
so dosesn't represent direct variation.
(2)Soln:-Here the given equation is,
2y=6x
y=3x ----(1)
For direct variation we have:
y=kx where k is the constant of variation.
since the equation (1) in form of y=kx ,
so it represent direct variation and constant is k=3
For each equation, determine whether it shows a direct variation (that is, shows directly proportional variables)....
