Yes; $k$=$\frac{7}{3}$
Equation: $-4+7x+4=3y$ To start, combine like terms:$-4+4=0$, so we are left with $7x=3y$ The $y$ needs to be isolated so divide 3 on both sides of the equation:$\frac{7}{3}$$x=y Rewrite this so that the y is placed in front of the equal sign: y=$$\frac{7}{3}$$x$ This is proper direct variation form, so yes, it does represent direct variation. The constant of variation is $k$ in the equation $y=kx$, so it is $\frac{7}{3}$.
