Answer:
Step-by-step explanation:
The amount of water in the bathtub per minute:4/9-8/9=-4/9;
liquid after:1/3* (-4/9)=-4/27
The correct answer is a equal 2/3
Well, to find the slope, you'd have to rearrange the equation so that it is in slope-intercept form, y=mx+b.
3x-y=0
-y=-3x+0
y=3x+0
The slope would be 3/1, and the line intersects y at point (0,0).
Hope this helps :-)
