Water moves on a slope by gravity.
However, the Romans, discovered that if the slope was only 2o ( two degrees) from the horizontal, then the water would flow , without surging. To this end they built their aqueducts with this slope, so no machinery was required to make the water flow.
To lift water to a greater height, they used the Archimedean Screw., which was moved by a donkey/mule chasing a carrot around a rotating pole.

Why is the slope of water negative?
For water the line has a negative slope (vs carbon dioxide). This explains why ice floats since volume decreases with increasing pressure as we move upward on the phase diagram from solid to liquid water, the volume occupied by H20 decreases and thus water must be increasing in density.
Why is it easier to go down a slope than up a slope?
Gravity helps you move down the slope but works against you on the way up.
Do the slope of direct variation changes as you move along the graph?
No.
How does making the slope of an inclined plane less steep affect the amount of force needed to move an object?
It requires less force to move an object up an inclined plane if the slope is less steep.
What does slope the math term mean?
The slope of a line is the vertical change when you move one unit to the left or right.With a larger slope, a line becomes steeper, and with a smaller slope it becomes more shallow. y=mx+b This is an equation for a line. It's called the point-slope form. In this equation, m is the slope.
