Answer 2

One variable increases, the other one increases accordingly. Otherwise, it's inverse-proportional

On the graph, it depends.

If it is a straight-lined, if the slope is positive, than it is an increasing function. Or look at the angle between the line and x-axis or any line parallel to x-axis on the line's, if it is less than half of a pi radian, than it's also an increasing graph.
