## Algebra 1

Since the general form of a direct variation is y=kx,. lets substitute the value of x and y into this equation: -5=$\frac{1}{4}$k (Divide both sides by $\frac{1}{4}$) -20=k Now plug in this value of k into the standard form of a direct variation: y=-20x This is our equation the relates both x and y for this situation.
