Tool/Plotter to draw points (a scatter plot or a curve) on a graph or 2D plane (and connect points if needed) according to their coordinates.

Answers to Questions

How to plot dots (x,y)?

Use a graph with a 2-dimensional coordinate system, ie: a horizontal axis $ x $ and a vertical axis $ y $.

Locate the position of each coordinate of the points on each axis, by positioning the value of the abscissa on the axis $ x $ and the value of the ordinate on the axis $ y $.

The position of the point is at the intersection of the vertical line passing through the abscissa and the horizontal line passing through the ordinate.

Example: $ (x,y) = (1,2) $, the point is in position $ x = 1 $ and $ y = 2 $

Draw a line between each point found and the next, so as to form a curve in parts.

The path obtained can possibly represent a drawing if the dot order is preserved.

How to find the function that correspond to the dots?

There are interpolation methods that allow you to create an equation that goes through the points. See Lagrange's interpolation or Neville's interpolation.
