Let y vary directly with x, with a constant of variation k=3. Graph the equation of varation.
--------------------------
Direct variation implies y = kx
You are told k=3.
EQUATION:
y=3x

The equation to use for this problem is: y=kx
Since k=3, your equation is -
y=3x
So, your slope is going to be 3 (or 3/1 if that's easier to understand).
