Answer:

no, it does not

Step-by-step explanation:

Hello

-x+4y=-5

$4y = x-5\\ y=\dfrac{1}{4}x-\dfrac{5}{4}$

we say that y varies directly with x if y=kx

in this example we have an additional constant, the graph is not a line through the origin so this is not a direct variation

hope this helps
