The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."

What is a curved line graph called?
nonlinear line
How do you draw a curved line on a graph from the equation?
i dont think there is such thing as the equation of a curved line the closest is probably a (hyperbola, ellipse, or parabola) with a restriction making it look like a curved line but it would be very complicated
Is a curved line linear?
No, "linear" means in a straight line.
Why don't all the points fall exactly on the curved line on a line graph?
You don't say what the curved line is so it is impossible to say. Is it a case of insufficient accuracy of measurement?
What is an arc in geometry?
Basically, a curved line.
